Terrific.  Certainly no problem about any confusion.  In that spirit, I 
just want to doublecheck:  you're now OK with what I've drafted?  If so, 
the only outstanding comment is Henry's on DTDs.  I think he and I have 
agreed privately that I can deal with that by emphasizing that the infoset 
at the original sender is a what Infoset calls a synthetic infoset [1] 
(I.e. not in general the result of a document parse), and by replacing the 
quote from the draft rec that says:

"The XML infoset of a SOAP message MUST NOT contain a document type 
declaration information item."

With the fuller quote

"A SOAP message is specified as an XML Infoset that consists of a document 

information item with exactly one member in its [children] property, which 

MUST be the SOAP Envelope element information item (see 5.1 SOAP 
Envelope). This element information item is also the value of the 
[document element] property. The [notations] and [unparsed entities] 
properties are both empty. The [base URI], [character encoding scheme] and 

[version] properties can have any legal value. The [standalone] property 
either has a value of "yes" or has no value.

The XML infoset of a SOAP message MUST NOT contain a document type 
declaration information item."

Any disagreement with this strategy?

You are right, it is covered.  Sorry.  That is all the rest of my 
message was discussing.

Thanks for your help on these issues.

While I think that these "tradeoffs" could be seen as possible reasons 
for applications not to subset XML on their own, I hope they are seen as 
reasons for the TAG to standardize a subset that matches SOAP that could 
encourage tools that support the subset that permit efficient processing 
of the subset, detection of violations, development of more subset 
applications that will more-directly interoperate, etc.
