1. Introduction
The document details an extension to the Manufacturer Usage
Description (MUD) mechanism to be able to mark one or more ACLs as
being enabled even though the device has been quaranteed.
2. Requirements Language
In this document, the key words "MUST", "MUST NOT", "REQUIRED",
"SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY",
and "OPTIONAL" are to be interpreted as described in BCP 14, RFC 2119
[RFC2119] and indicate requirement levels for compliant STuPiD
implementations.
3. MUD file extensions
