New issue: Use SOAP 1.2 properties where possible in describing SOAP 1.2 behavior.

The current resolution to CR 15 reads (in part):

When "http://www.w3.org/@@@@/@@/addressing/anonymous" is specified  
for the response endpoint and the request is the request part of a  
SOAP request-response MEP [soap 1.2 adjuncts ref], then any response  
MUST be the response part of the same SOAP request-response MEP [soap  
1.2 adjuncts ref].

The "response part of the ... SOAP request-response MEP" is a property
of the MEP denoted by the URI
http://www.w3.org/2003/05/soap/mep/OutboundMessage.  Given this, the
intended semantics may be stated more precisely as

When "http://www.w3.org/@@@@/@@/addressing/anonymous" is specified  
for the response endpoint and the request is the request part of a  
SOAP request-response MEP [soap 1.2 adjuncts ref], then the value of
the http://www.w3.org/2003/05/soap/mep/OutboundMessage property of the
same SOAP request-response MEP MUST be the response.

The statement for section 3.6.2 should be similarly reworded.  In
general, any discussion of SOAP 1.2 behavior should refer to
already-defined features and properties wherever possible.
