'SOAP' would not need to be packaged in another envelope, but the PGP
signed/encrypted paramater would need to be represented in a way that would
enable it to be inserted into a valid XML document as a sub-tree.
This is the exact situation that XMTP
(http://jabr.ne.mediaone.net/documents/xmtp.htm)
handles. XMTP is a mechanism to represent SMTP/MIME messages in valid XML,
as such the XMTP converted PGP document can be inserted into the XML
envelope as the 'parameter'. What this does in effect is create an XMTP
document envelope which represents whatever you would otherwise represent in
MIME. E.g. (simplified for readability)
<MIME>
<Content-type>multipart/encrypted</Content-type>
<Parts>
<MIME>
<Content-ID>document</Content-ID>
<Content-transfer-encoding>base64</Content-transfer-encoding>
<Body>...</Body>
</MIME>
<MIME>
<Content-ID>signature</Content-ID>
<Body>...</Body>
</MIME>
</Parts>
</MIME>
So, the answer is yes :-)
