JSContact: Converting from and to vCard
draft-ietf-calext-jscontact-vcard-15
Abstract
This document defines how to convert contact information between the
JSContact and vCard data formats. To achieve this, it updates RFC I-
D.ietf-calext-jscontact (JSContact) by registering new JSContact
properties. Similarly, it updates RFC 6350 (vCard) by registering
new vCard properties and parameters.

1. Introduction
Loffredo & Stepanek Expires 5 September 2024 [Page 4]
Internet-Draft jscontact-vcard March 2024
1.1. Motivation
The JSContact data model and format [I-D.ietf-calext-jscontact] aims
to be an alternative to the widely used vCard [RFC6350] standard and
jCard [RFC7095].
While applications might prefer JSContact to exchange contact card
data with other systems, they are likely to interoperate with
services and clients that only support vCard or jCard. Similarly,
existing contact data providers and consumers already using vCard or
jCard might want to represent their contact data also in JSContact.
To achieve this, this document defines standard rules to convert
contact data between JSContact and vCard (and consequently jCard).
1.2. Notational Conventions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in
BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
1.3. ABNF Notations
The ABNF definitions in this document use the notations of [RFC5234].
ABNF rules not defined in this document either are defined in
[RFC5234] (such as the ABNF for CRLF, WSP, DQUOTE, VCHAR, ALPHA, and
DIGIT) or [RFC6350].
2. Converting vCard to JSContact
This section contains the conversion rules from vCard to JSContact
Card. It follows the same structure as the vCard v4 [RFC6350].
Properties and parameters of vCard extension RFCs, including the
vCard JSContact Extension
[I-D.ietf-calext-vcard-jscontact-extensions] are added to appropriate
subsections.
2.1. General rules
Loffredo & Stepanek Expires 5 September 2024 [Page 5]
Internet-Draft jscontact-vcard March 2024
2.1.1. The uid property
The UID property in vCard is optional, but the uid property in
JSContact is mandatory. Implementations that convert a vCard without
UID property MUST generate a unique identifier as a value for the uid
property. This value SHOULD be the same when converting the same
vCard multiple times, but how to achieve this is implementation-
specific.
2.1.2. Choosing identifiers
Multivalued properties in JSContact typically are represented as a
JSON object where the object keys are of the Id type and the object
values are the converted vCard property. In absence of the PROP-ID
parameter (see Section 2.3.16), implementations are free to choose
any identifier for such entries. Whatever identifier generation
scheme implementations use, they MUST generate values that are valid
according to the definition of the Id type in
[I-D.ietf-calext-jscontact]. For example, this could be an
incrementing number across all Ids or only unique within one JSON
object.
2.2. vCard Value Data Types
2.2.1. BOOLEAN
This converts to the JSContact Boolean type.
2.2.2. DATE, TIME, DATE-TIME, DATE-AND-OR-TIME, and TIMESTAMP
The TIMESTAMP type generally converts to the UTCDateTime. It
converts to the Timestamp type for anniversaries.
The DATE type converts to the PartialDate type, which only is
relevant for anniversaries. This does not apply to DATE values that
only define a month or a day.
The TIME, DATE-TIME, DATE-AND-OR-TIME types and DATE type values that
only define a month or day do not convert to a JSContact datetime
type. Instead, vCard properties or parameters having such values
convert to the properties defined in Section 2.15.
2.2.3. INTEGER
This converts to the JSContact Int and UnsignedInt types.
Loffredo & Stepanek Expires 5 September 2024 [Page 6]
Internet-Draft jscontact-vcard March 2024
2.2.4. FLOAT
This converts to the JSContact Number type.
2.2.5. LANGUAGE-TAG
This converts to the JSContact String type.
2.2.6. TEXT
This converts to the JSContact String type.
2.2.7. URI
This converts to the JSContact String type.
2.2.8. UTC-OFFSET
This either converts to a String containing an IANA TimeZone Database
entry name (see Section 2.8.2), or it does not convert to any
JSContact type. For the latter, vCard properties or parameters
having such values MAY convert to JSContact as defined in
Section 2.15.
2.3. vCard Parameters
This section contains the conversion rules for vCard parameters. A
rule typically only applies for specific vCard properties. To
convert a vCard parameter on an arbitrary vCard property, see
Section 2.15.2.
2.3.1. ALTID
This does not convert to an IANA-registered property in JSContact,
but several conversion rules make use of this parameter to combine
multiple vCard properties into a single JSContact object instance.
For an example of this see Section 2.6.1. To preserve the verbatim
value of the ALTID parameter, set the JSContact properties defined in
Section 2.15.
2.3.2. AUTHOR
The AUTHOR parameter value of a vCard NOTE property converts to the
uri property of the Author object for this note.
Note: This parameter is defined in
[I-D.ietf-calext-vcard-jscontact-extensions].
Loffredo & Stepanek Expires 5 September 2024 [Page 7]
Internet-Draft jscontact-vcard March 2024
2.3.3. AUTHOR-NAME
The AUTHOR-NAME parameter value of a vCard NOTE property converts to
the name property of the Author object for this note.
Note: This parameter is defined in
[I-D.ietf-calext-vcard-jscontact-extensions].
2.3.4. CALSCALE
This parameter set on a BDAY, DEATHDATE or ANNIVERSARY property
converts to the calendarScale property of the PartialDate object
type.
2.3.5. CREATED
The CREATED parameter value of a vCard NOTE property converts to the
created property of the Note object.
Note: This parameter is defined in
[I-D.ietf-calext-vcard-jscontact-extensions].
2.3.6. DERIVED
If this parameter is set to true on a vCard property, then
implementations MAY choose to not convert that property.
Note: This parameter is defined in
[I-D.ietf-calext-vcard-jscontact-extensions].
2.3.7. GEO
This parameter set on an ADR property converts to the JSContact
coordinates property of the Address object that represents the vCard
ADR.
2.3.8. GROUP
This parameter exclusively is for use in jCard (see Section 7.1 of
[RFC7095]). It MUST NOT be set in a vCard. Preserving the exact
group name when converting from vCard to JSContact and back to vCard
is not necessary. Any group identifiers will do, as long as the
resulting vCard groups its properties equally to the original vCard.
Implementations that still wish to preserve the exact property group
name of a vCard property MAY set the group parameter in the JSContact
properties vCardProps or vCardParams defined in Section 2.15.

2.3.9. INDEX
This parameter set on the EXPERTISE, HOBBY, INTEREST and ORG-
DIRECTORY properties defined in [RFC6715] converts to the JSContact
listAs property of the PersonalInfo and Directory objects.
2.3.10. LANGUAGE
This converts to an entry in the localizations property for the vCard
property that this parameter is set on. The value of the LANGUAGE
parameter defines the language tag key in the localizations property.
This specification does not define a single standard conversion rule
for how to convert the property values. Instead, building the
localizations value is implementation-specific.
Two options to populate the localizations property are:
Loffredo & Stepanek Expires 5 September 2024 [Page 9]
Internet-Draft jscontact-vcard March 2024
* One Patch Per Property: For each vCard property with a LANGUAGE
parameter, set the complete path in the PatchObject to the
JSContact property that the vCard property converts to. The value
of the patch is the converted property value. This is simple to
process and adequate if the vCard only contains a few properties
with LANGUAGE parameter.
* Bundle Patches by Parent: If a PatchObject contains multiple paths
that have the same parent paths, then it might be possible to
combine these patches into one patch that patches the parent
property. This is possible if the property in the Card is patched
in its entirety.
Generally, localizations only localize properties that are present in
the non-localized version of this Card. Figure 3 illustrates this.

}
}
Figure 3: LANGUAGE conversion example: one dominant language
As a special case, if one or more vCard properties of the same type
do not have the LANGUAGE parameter set, then choose them to the non-
localized Card. Convert any with LANGUAGE parameters to the
localizations property. Figure 4 illustrates this.

}
}
Figure 4: LANGUAGE conversion example: property without language
As the least preferred option, Figure 5 illustrates how all vCard
properties of the same type have the LANGUAGE parameter set, but none
of their language tags match the language of the main Card. In this
case, implementations MAY choose to add the localized vCard
properties only to the localizations object.
The following example uses non-ASCII characters to demonstrate
multilingual content. The ASCII-formatted version of this
specification might not show the correct characters. Please refer to
the HTML or PDF versions instead.

property and parameter values
2.3.11. LEVEL
The LEVEL parameter [RFC6715] converts to the level property of the
PersonalInfo type. If this parameter is set on the EXPERTISE
property, then its values convert as:
* "beginner" converts to "low";
* "average" converts to "medium";
* "expert" converts to "high".
In all other cases the values convert verbatim, but lowercase MUST be
used for the JSContact value.
2.3.12. MEDIATYPE
This converts to the mediaType property of the Resource object type.
2.3.13. PHONETIC
This parameter as well as the SCRIPT (Section 2.3.17) parameter set
on a N or ADR property convert to JSContact as follows:
Loffredo & Stepanek Expires 5 September 2024 [Page 12]
Internet-Draft jscontact-vcard March 2024
the values of the phonetic, phoneticScript and phoneticSystem
properties of the NameComponent and Name or AddressComponent and
Address object types, respectively.
The related N or ADR property is defined by the vCard ALTID
parameter. The conversion rules for the N (Section 2.5.5) and ADR
(Section 2.6.1) properties define how the vCard components convert to
JSContact.
The value of the PHONETIC parameter converts to the phoneticSystem
property unless it is script, in which case the phoneticSystem
property is not set. The value of the SCRIPT parameter converts to
the phoneticScript property.
The values of the components in the property value convert to values
the phonetic properties for the respective NameComponent or
AddressComponent.
If more than one property having the PHONETIC parameter set relates
to the same property, then they convert to the Card localizations
property according their LANGUAGE parameter values as outlined in
Section 2.3.10.

2.5.2. FN
The FN property converts to the Name object in the name property.
Its value converts to the Name object full property (Figure 11). If
the LANGUAGE parameter is set, then the FN property converts as
outlined in Section 2.3.10. In the unexpected case that the vCard
contains more than one FN property without LANGUAGE parameter, then
convert the FN property that has the least parameters set to the full
property. If multiple such FN properties are present, choose any of
them. All other FN properties convert to the vCardProps
(Section 2.15.1) property.
FN:John Q. Public, Esq.
"name": {
"full": "John Q. Public, Esq."
}

A value of type UTC-OFFSET converts to the timeZone property in the
Address object if the offset has zero minutes and the hour offset is
in the range -12 <= 14:
* If the hour offset is zero, use the time zone name Etc/UTC.
* Otherwise construct the time zone name with Etc/GMT suffixed with
the string representation of the reversed sign hour offset,
including the sign but excluding leading zeros and minutes. For
example, the UTC offset value -0500 converts to Etc/GMT+5.
Loffredo & Stepanek Expires 5 September 2024 [Page 29]
Internet-Draft jscontact-vcard March 2024
For such property values, also see Section 2.8.3 to determine which
Address object instance to convert to.
Any other value of type UTC-OFFSET or URI does not convert to an
IANA-registered property in JSContact. To convert such property, see
Section 2.15.1.
2.8.3. Combining geographical properties
In vCard the properties ADR, GEO and TZ occur independently of each
other. In JSContact, they all convert to properties of an Address
object. It is implementation-specific if these vCard properties
convert to _separate_ address instances in JSContact, or if some or
all of them convert to the _same_ address. That being said,
implementations MUST convert the properties to the _same_ address for
the following cases:
* The GROUP parameter values of the properties match.
* The GROUP parameters are not set, but are set on any other ADR,
GEO and TZ properties.
2.9. Organizational Properties
2.9.1. CONTACT-URI
A CONTACT-URI property as defined in [RFC8605] is represented as an

2.14. Extended Properties and Parameters
These convert as specified in Section 2.15.
2.15. New JSContact properties
vCards may contain properties or parameters for which no IANA-
registered JSContact property is defined. For example, a vCard may
contain properties and parameters of which the semantics or purposes
are unknown to the implementation; see Section 6.10 of [RFC6350].
This section defines JSContact properties by which such vCard
properties and parameters MAY be represented in JSContact.
Implementations MAY choose to convert differently if they deem that
more appropriate.
2.15.1. Property vCardProps
Name: vCardProps
Type: JCardProp[], where JCardProp denotes a jCard-encoded vCard
property as defined in Section 3.3 of [RFC7095].
Definition: This property is set on a JSContact object that
represents a vCard. It contains properties that are set in the
vCard represented by this JSContact object. Each entry in this
list typically represents a vCard property for which no conversion
to an IANA-registered JSContact property is defined.
Example: This illustrates how to convert a vCard extension property:
Loffredo & Stepanek Expires 5 September 2024 [Page 43]
Internet-Draft jscontact-vcard March 2024
item1.X-FOO;X-BAR=Hello:World!
"vCardProps": [
["x-foo", {
"x-bar": "Hello",
"group": "item1"
}, "unknown", "World!"]
]
Figure 46: JSContact vCardProps example
2.15.2. Property vCardParams
Name: vCardParams
Type: String[String|String[]]
Definition: This property is set on a JSContact object that
represents a vCard property. Its value MUST be a JSON object
containing vCard property parameters, defined as array element 2
in Section 3.3 of [RFC7095]. Each entry represents a parameter of
the vCard property that converts to the JSContact object.
Example: This illustrates how to convert a vCard extension
parameter:
EMAIL;X-FOO=Bar:jane_doe@example.com
"emails": {
"email1": {
"address": "jane_doe@example.com",
"vCardParams": {
"x-foo": "Bar"
}
}
}
Figure 47: JSContact vCardParams example
2.15.3. Property vCardName
Name: vCardName
Type: String
Definition: This property is set on a JSContact object that
Loffredo & Stepanek Expires 5 September 2024 [Page 44]
Internet-Draft jscontact-vcard March 2024
represents a vCard property or parameter and its value contains
the name of that vCard element. This allows to preserve the name
of a vCard element when multiple elements convert the same
JSContact object type. The case-insensitive value MUST be valid
according to the name ABNF defined in Section 3.3 of [RFC6350].
Example: Both vCard IMPP and SOCIALPROFILE convert to OnlineService
in JSContact. The vCardName property value indicates that the
vCard source element was IMPP:
IMPP:xmpp:alice@example.com
"onlineServices": {
"os1": {
"uri": "xmpp:alice@example.com",
"vCardName": "impp"
},
}
Figure 48: JSContact vCardName example
3. Converting JSContact to vCard
3.1. Conversion Rules
A Card converts to vCard by applying the reverse rules of converting
vCard to JSContact. In addition to those listed in Appendix A, the
following rules apply:
* Multivalued JSContact properties convert to separate instances of
their equivalent vCard property, and for each the PROP-ID
parameter MUST be set to the Id of the converted value (see
Section 2.3.16).
* The full property of the name property in JSContact is optional,
but the FN property is mandatory in vCard. The following rules
apply:
- If the Name full property is set, then implementations MUST use
its value for the vCard FN property.
Loffredo & Stepanek Expires 5 September 2024 [Page 45]
Internet-Draft jscontact-vcard March 2024
- If the Name full property is not set, then implementations
SHOULD derive the full name from the Name components values.
If the isOrdered property is true, then this can be done by
concatenating the name component values. Otherwise, or
alternatively, an implementation can choose any other heuristic
to generate the full name from its components, such as
[CLDRPersonName]. Implementations MUST set the DERIVED
parameter on the FN property.
- Otherwise, they MUST set the FN property to the empty value.
* Vendor-specific and unknown properties convert to vCard as
outlined in Section 3.1.1.
3.1.1. Converting unknown properties
JSContact object types may contain properties for which no IANA-
registered vCard property is defined. For example, a JSContact
object may contain vendor-specific properties of which the semantics
or purpose are unknown.
This specification defines the new JSPROP (Section 3.2.1) vCard
property and JSPTR (Section 3.3.2) vCard parameter by which such
JSContact properties MAY be represented in vCard. Implementations
MAY choose to convert differently if they deem that more appropriate.
3.2. New vCard Properties
3.2.1. JSPROP
Property name: JSPROP
Purpose: This property represents a JSContact property in vCard.
Value type: TEXT, also see Format Definition for value restrictions.
Conformance: The property can be specified multiple times in a
vCard.
Property parameters: The JSPTR parameter MUST be set for this
property. Other IANA-registered and experimental property
parameters can be specified on this property.
Description: This property converts an arbitrary JSContact property
Loffredo & Stepanek Expires 5 September 2024 [Page 46]
Internet-Draft jscontact-vcard March 2024
from and to vCard. The vCard property value is the JSON-encoded
value of the JSContact property, represented as a TEXT value. The
format of the JSON value MUST be compact, e.g., without
insignificant whitespace. The value of the JSPTR parameter points
to the JSContact property within the Card.
The root of the JSON pointer is always the Card object that this
vCard converts to, irrespective if the JSON pointer starts with
the SOLIDUS (U+002F) character. The pointer MUST NOT reference
into an array.
All JSPROP properties in a vCard together form a PatchObject as
defined in [I-D.ietf-calext-jscontact]. The value of its JSPTR
parameter corresponds to a key in the PatchObject, the value of
the JSPROP property corresponds to the value for that key. When
converting from vCard to JSContact, the PatchObject MUST only be
applied after all other vCard properties have already been
converted. The PatchObject MUST be valid, including the
restriction that an invalid PatchObject MUST NOT be applied.
Format definition: This property is defined by the following
notation:
jsprop = "JSPROP" jsprop-param ":" TEXT
jsprop-param = *(
; The following are MANDATORY and MUST NOT
; occur more than once
( ";" jsptr-param ) / ; see next section
( ";" "VALUE" "=" "TEXT")
;
; The following is OPTIONAL,
; and MAY occur more than once.
;
(";" other-param)
;
)
Example(s): This illustrates how to convert a property at the top-
level in a Card object that is unknown to the implementation.
"someUnknownProperty": true
JSPROP;JSPTR="someUnknownProperty":true
Figure 49: Unknown property example
Loffredo & Stepanek Expires 5 September 2024 [Page 47]
Internet-Draft jscontact-vcard March 2024
This illustrates how to convert a vendor-specific property at the
top-level of a Card object. Note the required use of quoted
string for the JSPTR value which allows the path to include the
COLON (U+003A) character.
"example.com:foo": {
"bar": 1234
}
JSPROP;JSPTR="example.com:foo":{"bar":1234}
Figure 50: Vendor-specific property conversion example
This illustrates how to convert a vendor-specific property at a
nested level in a Card object using a path relative to the Card
object. Although not recommended, the property name includes the
SOLIDUS (U+002F) character which requires escaping in the JSON
pointer.
"phones": {
"phone1": {
"number": "tel:+33-01-23-45-67",
"example.com:foo/bar": "tux hux"
}
}
TEL:tel:+33-01-23-45-67
JSPROP;JSPTR="phones/phone1/example.com:foo~1bar":
"tux hux"

relative to Card
3.3. New vCard Parameter
3.3.1. JSCOMPS
Parameter name: JSCOMPS
Purpose: This parameter defines the order and separators for the
elements of a structured property value.
Description: The JSCOMPS parameter value facilitates converting name
and address components between JSContact and vCard. It preserves
the order of the components the JSContact property and contains
the verbatim values of separator components.

If this parameter is set and its value is valid (see later), then
implementations MUST set the isOrdered property of the Name or
Address object to "true". Otherwise, they MUST set the isOrdered
property value to "false".
The JSCOMPS parameter value is a structured type value. Its value
MUST be quoted. The parameter value consists of a sequence of
entries, separated by the SEMICOLON character (U+003B). The first
entry defines the value of the defaultSeparator property. If it
is the empty string then no default separator is defined.
Otherwise, the first entry MUST be a separator entry. All
following entries processed in order result in an ordered list of
JSContact components, and MUST be one of two following two kinds:
1. A positional. This refers to a component value in the vCard
structured value A position consists of the numeric index of a
component in the structured value, optionally followed by a
COMMA (U+002C) character and the non-zero index of a value
within that component. The zero index selects the first
component or value, respectively. The second index by default
is zero, in which case it MUST be omitted (as well as the
leading COMMA).
The resulting JSContact component is formed by determining its
kind by the position in the vCard structured value. The
component value is the verbatim value of the vCard component.
Figure 52 and Figure 53 illustrate this by example.
2. A separator. This contains the verbatim value of a separator
component. It starts with the LATIN SMALL LETTER S (U+0073)
character, followed by COMMA (U+002C), followed by zero or
more Section 3.3 of param-value [RFC6350] characters, where
the COMMA (U+002c) and SEMICOLON (U+003B) character MUST be
escaped according to the rules defined in Section 3.4 of
[RFC6350]. Figure 54 illustrates this by example.
The resulting JSContact component is formed by setting its
kind to separator and its value to the verbatim value of the
entry.
A JSCOMPS parameter value is valid if and only if:
* All indexes in the positional entries refer to an existing
component value in the vCard property value.
Loffredo & Stepanek Expires 5 September 2024 [Page 49]
Internet-Draft jscontact-vcard March 2024
* The count of positional entries equals the count of
deduplicated component values. Deduplication is required
because some values may occur in both their designated and
backwards-compatible components in the vCard property value:
- A value that occurs in both the N property secondary surname
component and the family name component only counts once.
- A value that occurs in both the N property generation
component and the honorific suffix component only counts
once.
- A value in the ADR property street address component does
not count if the ADR property value contains a value in one
of the new components defined in
[I-D.ietf-calext-vcard-jscontact-extensions].
- All other values count once each.
Format definition:
jscomps-param = "JSCOMPS" "="
DQUOTE (
(jscomps-entry-sep / "") ";" jscomps-entrylist
) DQUOTE
jscomps-entrylist = jscomps-entry *(";" jscomps-entry)
jscomps-entry = jscomps-entry-pos / jscomps-entry-sep
jscomps-entry-pos = 1*DIGIT [ "," 1*DIGIT ]
jscomps-entry-sep = "s" "," jscomps-entry-verb
jscomps-entry-verb = *QSAFE-CHAR ; encode special characters according to RFC 6868
Example(s): The following example demonstrates the use of positional
entries for the name "Jane Doe". The given name is ordered before
the surname. No secondary index is required for either positional
because both are zero.
"name": {
"components": [
{ "kind": "given", "value": "Jane" },
{ "kind": "surname", "value": "Doe" }
],
"isOrdered": true
}
N;JSCOMPS=";1;0":Doe;Jane;;;;;;
FN;DERIVED=TRUE:Jane Doe

Loffredo & Stepanek Expires 5 September 2024 [Page 50]
Internet-Draft jscontact-vcard March 2024
The following example demonstrates a secondary positional index.
The "Jr." generation marker only counts once because it occurs in
both the designated generation component and the backwards-
compatible honorific suffixes component.
"name": {
"components": [
{ "kind": "given", "value": "John" },
{ "kind": "given2", "value": "Philip" },
{ "kind": "given2", "value": "Paul" },
{ "kind": "surname", "value": "Stevenson" },
{ "kind": "generation", "value": "Jr." },
{ "kind": "credential", "value": "M.D." }
],
"isOrdered": true
}
N;JSCOMPS=";1;2;2,1;0;6;4,1":Stevenson;John;Philip,Paul;;Jr.,M.D.;;Jr.
Figure 53: Example for positional entries
The following example demonstrates the use of separator entries
for the (shortened for brevity) address "54321 Oak St, Reston".
The first entry defines the default separator to be ", ". The
second and fourth positional entries are separated with the
separator value " ". For backwards-compatibility, the street
address component of the ADR property contains both the street
number and name, but it is not referred to in the JSCOMPS
parameter and does not contribute to the count of values.
"addresses": {
"a1": {
"components": [
{ "kind": "number", "value": "54321" },
{ "kind": "separator", "value": " " },

3.3.2. JSPTR
Parameter name: JSPTR
Purpose: This parameter contains a JSON pointer [RFC6901] that
relates the vCard JSPROP (Section 3.2.1) property to a JSContact
property.
Description: This parameter has a single value that MUST be a valid
JSON pointer as defined in [RFC6901]. Note that the value MUST be
quoted according to the param-value ABNF in [RFC6350].
Format definition:
jsptr-param = "JSPTR" "=" param-value
; also see param-value in RFC 6350, section 3.3
Example(s): This illustrates a simple example. For further examples
see Section 3.2.1.
JSPROP;JSPTR="example.com:foo":"bar"
4. Security Considerations
This specification defines how to convert between the JSContact and
vCard formats. The security considerations for parsing and
formatting such data apply and are outlined in Section 5 of
[I-D.ietf-calext-jscontact] and Section 9 of [RFC6350].
5. Acknowledgements
The definition and examples of the PHONETIC (Section 2.3.13) and
SCRIPT (Section 2.3.17) parameters are based on the initial version
of [I-D.calconnect-vobject-i18n].
