Would it be possible to qualify the MUST requirement on part 1 to
indicate that one can implement, say, only a SOAP sender? That is, we
state the intent in terms of "if you do X then you MUST do all required
parts of X"? Maybe something like this:

<HFN_revised_proposal>
1.@@ Conformance

In order for an implementation to claim conformance with the SOAP 1.2
specification, it MUST implement all mandatory ("MUST") requirements
expressed in Part 1 of the SOAP 1.2 specification necessary to implement
the functionality needed by that implementation. That is, an
implementation designed to be a SOAP sender MUST implement all mandatory
requirements to SOAP senders, a SOAP message MUST fulfill all mandatory
requirements to SOAP messages and so forth.

An implementation MAY implement any number of the Adjuncts specified in
Part 2 of the SOAP 1.2 specification. (Note there is no conformance
associated with the convention for describing features and bindings
[ref]). The implementation of an Adjunct MUST implement all of the
mandatory requirements expressed in the specification of the Adjunct to
claim conformance with the Adjunct.

The conformance of any other technologies allowed within the scope of
the SOAP 1.2 specification is out of scope of the SOAP 1.2
specification. It is recommended that such technologies provide their
own conformance rules. 

SOAP 1.2 is designed to enable at least the usage scenarios described in
SOAP Version 1.2 Usage Scenarios [ref], and possibly other scenarios.
Informal descriptions showing XML representations of concrete SOAP
messages used in some common scenarios are provided in SOAP Version 1.2
Part 0: Primer [ref].
