I'd like to point out a couple of notes I sent on this subject last week 
[1] and [2], which I will briefly summarize here: 

First of all, processing DTDs has a real cost in performance and 
complexity.  While you can process SOAP messages with any XML processor, 
you can also write much faster processors for SOAP that don't mess with 
things like user-defined entities.  PI's complicate the model, and for 
questionable benefit (see note [1]).  So, adding these features back into 
SOAP is not free.  I think we should leave them out.  Many applications of 
XML use only a subset of its features (note [2])...SOAP is another 
application of XML and it should use the features that it needs.
