I do not think this is clear enough. I think that each statement 
throughout the specification that requires conformance from a user agent 
should use terminology that indicates this.

The QA Framework: Specification Guidelines 
(http://www.w3.org/TR/2005/REC-qaframe-spec-20050817) requirement 7 states:

          Use a consistent style for conformance requirements and
          explain how to distinguish them

Requirement 8 states:

          Indicate which conformance requirements are mandatory, which
          are recommended, and which are optional.

Specifying in section 3.2 that a UA must conform with the rest of the 
specification does not make it easy to distinguish conformance 
requirements. Nor does it make it easy to determine which comments are 
mandatory, recommended or optional.

Where are these musts you indicate that apply to section 6.1.3? they are 
not linked to section 6.1.3.

No, this does not address my concerns.
