I wouldn't say it's lost, I'd just say that it's changed.

A SOAP based encryption mechanism would still protect the *content*

this is a much better layered solution in the general case.

No, I wasn't suggesting copying, I was suggesting moving.  Leaving
the same information in more than one place in the message is just
asking for trouble IMO (SOAPAction anyone? 8-).
