RE: i67 and i68 proposal for WSDL doc

Text along these lines would be clearer. I also think 3.4.2 should be HTTP
specific (and I updated the text accordingly).

=================================================

3.4.1 SOAP 1.1/HTTP binding

WS-Addressing changes the SOAP 1.1/HTTP binding used when the value of the
response endpoint EPR contains an address different from the WS-Addressing
anonymous URI. In this case, the receiver of a message MUST use a binding
that supports not returning a SOAP envelope in the HTTP response (such as
[URI for binding doc]) unless a different behavior is mandated for the URI
specified in the response endpoint EPR address by another specification
that is supported by the endpoint.  Absent such a requirement by another
specification, if the value of the response endpoint EPR contains an
address that is different from the WS-Addressing anonymous URI, then the
outbound message MUST be sent using a separate connection and using the
address value specified by response endpoint.

3.4.2 SOAP 1.2/HTTP binding

When the value of the response endpoint EPR contains the anonymous address
and the request is the request part of a SOAP request-response MEP [soap
1.2 adjuncts ref], then the response must be the response part the same
SOAP request-response MEP [soap 1.2 adjuncts ref].  When the value of the
response endpoint EPR contains a value different from the anonymous address
then any response message is not part of the mep that the request message
is in.
