May I ask why you would preclude use of 1.1 envelopes? It would seem to 
be counter-productive to tie this media type to specific versions of 
SOAP.

I don't think we had a concern specifically with any language in the 
document. We had an internal argument about whether or not we could use 
SOAP 1.1 envelopes with the media type, and decided that the 
registration did not clearly address this. We wanted to recommend that 
the registration be amended to clearly not preclude use of SOAP 1.1 
with the media type. If the WG doesn't want to do that, then probably 
the next best thing from our point of view is to leave any language 
sufficiently unclear as to not disallow SOAP 1.1 + media type ;)

Seriously, though, I do think it would be worth making some kind of 
statement in the registration that notes that the media type is not 
dependent on any particular version of SOAP, as long as future versions 
remain backwards-compatible with SOAP 1.2. From a Liberty point of 
view, I would like to see something like "The application/soap+xml 
media type is intended for use with SOAP envelopes serialized with XML, 
and is not dependent on the version of the SOAP envelope (as defined in 
SOAP Versioning Model [SOAP121]) being serialized."
