This isn't a correct characterization at all. You CAN access attachments 
with creative use
of an URIResolver for the MIME multipart envelope. You CAN indeed 
process the SOAP
envelope AND the attachments using XSLT and a URIResolver that is aware 
of the MIME
envelope. You can also effectively slurp an attachment XML document into 
the SOAP Body
element using an XSLT document() call and a URIResolver. This is pretty 
stuff. You do NOT need to have the document physically *in* the SOAP 
envelope when
it is on the wire, and IMO it is pretty trivial to make it appear as if 
it were.
