Why would anything need to
go in the header? The spec that defines the header would define what if
any relationship it had to body content.

Subject: [ws-rx] issue 115: clarifying question
 
During the conference call
of 4/20/2006 Chris asserted that you can use a SOAP header with a mustUnderstand
attribute to flag the fact that some element in either another header or
in the message body is an extension that must be understood by the receiver.
I'm not sure I understood exactly what Chris thought this should look like.
For example, imagine the following CreateSequence message. The extension
elements have been marked in bold. What is supposed to go in the <wsrm:Extension>
header?

<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://www.w3.org/2003/05/soap-envelope"
xmlns:wsrm="http://docs.oasis-open.org/ws-rx/wsrm/200604"
xmlns:wsa="http://www.w3.org/2005/08/addressing">
 <S:Header>
  <wsrm:Extension S:mustUnderstand="1">
    ????
  </wsrm:Extension>
  <wsa:MessageID>

    </wsrm:AcksTo>

      </wsrm:Identifier>
    </wsrm:SecurityComposition>
  </wsrm:CreateSequence>
 </S:Body>
</S:Envelope>

I'm sure that most of us could all come up with a reasonable design to
do what you suggest, but for the purposes of further discussion I'd like
to know what design Chris had in mind?
