Don Box asks:

>> Is there an Infoset 1.1? Are there plans for such a beast?

Since writing my note, it has been pointed out to me that the current 
Infoset provides under Document Information Item [1]:

"[version] A string representing the XML version of the document. This 
property is derived from the XML declaration optionally present at the 
beginning of the document entity, and has no value if there is no XML 

So, if you have a full document and a DII, then that's the place to signal 
XML versions.  I don't think there's a way to label an element info item 
in isolation.  In SOAP 1.2 we allow the DII and say [2]:

"The [base URI], [character encoding scheme] and [version] properties can 
have any legal value."

OK, but I'm not sure that when we did that we quite anticipated that a 
version of 1.1 would allow characters that were illegal in 1.1, and which 
can't be sent by the existing HTTP binding...at least it's my preliminary 
understanding that they can't.  I'd be glad for someone more knowledgeable 
to correct me. 

Anyway, I think we want to go over the spec. carefully and make sure that 
1.1 hasn't introduced any loose ends.


P.S. dropping xmlp-comments, as we are mainly using that to log initial 
announcement and final resolution for potential issues.  I think everyone 
on xmlp-comments is on distApp.
