I suggest that adding more to the WS-Reliability element names is
unnecessary, for the following reasons:

1. If users have to read even a fraction of one percent of Reliable
   messages, then there's something wrong somewhere.

2. If a user who doesn't understand how to read namespaced XML reads a
   raw SOAP message, there'll be more that the user doesn't understand
   than just the WS-Reliability headers.

3. The choice of prefix is not going to confuse the processors
   (although broken processors will increase the incidence of users
   reading messages, I admit).

4. With SOAP 1.2, at least, if your RMP puts a "wsrm" prefix on the
   WS-Reliability elements, then the prefix will remain the same even
   through forwarding intermediaries.

   http://www.w3.org/TR/2003/REC-soap12-part1-20030624/#soapinterminfoset
   says:

   22. All namespace information items in the [in-scope namespaces] of
       element information items MUST be preserved. Additional
       namespace information items MAY be added.

   and http://www.w3.org/TR/2001/REC-xml-infoset-20011024/#infoitem.namespace
   says a namespace information item has a prefix property.

   (SOAP 1.1 doesn't seem to say anything on the subject.)

5. There's nothing stopping anyone from defining a different SOAP
   Header with a local name of "RMRequest".
