It could also be that the actual encryption itself is handed over to an
intermediary which does this kind of task for all the soap processors. This
is most likely case especially after the message has been enriched with
private data. 

The key issue IMHO is that; Are we are asking for integrity protection on a
hop by hop basis or end to end basis? That clarification might be something
this WG should consider adding.

It could be that a sender might encrypt the header and allow the routing 
intermediary to decrypt it, right?
