CR20

This is my summary of the options I think we have to close CR20.

0. Get rid of the defaulting altogether. I don;t think anyone is pushing
for this option anymore.

1. Restrict the defaulting of To to the anonymous URI to response messages
only. This is fully consistent with the resolution of CR17, that restricts
the defaulting of ReplyTo (to the "anonymous EPR") to request messages.
Advantages: consistent approach to the use of defaults for optimizing the
synch request response patter, but leaving other potential issues
unmodified.

2. Ban the use of anonymous in the To field altogether. Disadvantage: does
not take into account the fact that anonymous has different meanings
depending of the transport.

3. Middle of the road approach: retain the defaulting of the To header to
anonymous, but re-state that its use is actually dependent on the
interpretation that the transport binding gives to the anonymous URI. Add a
note indicating that for the SOAP/HTTP case the anonymous URI is only used
to indicate the use of the HTTP back channel so it can only be used in
reply messages.

I think #3 provides an answer to CR 18 as well.
