And "and PI" to the above.  SOAP doesn't allow DTDs or PI's.

It's not quite that bad.  SOAP 1.2 is defined in terms of the infoset. 
(At the time, I argued against this and lost.)  While this mainly makes 
the spec more verbose and harder to read, it does allow one to create a 
SOAP message with DOM, and send it to someone else via SAX or suchlike. 
That might be a good thing.  However, the only defined mappings all say 
"serialize according to XML 1.0".

I think we're getting an interesting split in W3C specs: those that are 
defined in terms of the serialization, and those that are defined in 
terms of infoset.  The problem comes when the mix, such as when you want 
to sign or encrypt a SOAP message.  Seems like TAG fodder...
