See
http://lists.w3.org/Archives/Public/public-xml-core-wg/2007Nov/0038
for Martin's latest.

I think we are able to accept what it appears will be Martin's
wording in the next draft.

ACTION to Henry:  Send one more reply to Martin about "should
be as late as possible."

ACTION to Paul:  Ask Martin about scheduling.

In general, we are leaning toward allowing 1.0 processors
to process documents with any version value of the form 1.x.

Does a document have more than one "true (complete)" infoset?

A character reference to a C0 control is allowed in 1.1 but
not in 1.0.  If a 1.0 processor parses such a document, it
will throw an error.

Richard points out that a document with #x85 processed by a 1.0
processor will result in an infoset that isn't the same as
that gotten when processed by a 1.1 processor, and we won't
really know that we got a different result (unless the 5th Ed
processor decided to produce a warning).

If we allow this, we are saying that a document could have 
two different complete infosets, one when processed by a 1.0 
processor and the other when processed by a 1.1 processor.

ACTION to Henry:  Check with Noah how IBM feels about #x85.

See http://www.w3.org/TR/xml-infoset/#intro.versions
where it says:

 The information set of an XML document is defined to be
 the one obtained by parsing it according to the rules of
 the specification whose version corresponds to that of the
 document. A document which does not specify a version number
 is considered to have version 1.0. If an XML processor accepts
 a document with a version number that it does not understand,
 it will not necessarily be able to produce the correct
 information set. 

CONSENSUS to allow XML 1.0 processors to accept documents 
labelled version="1.1".

> 
> We asked if unlabelled documents would remain 1.0 or not. 
> MSM would like to say an unlabelled document can be attempted 
> to be processed by any processor whereas right now an unlabelled 
> document can only be a 1.0 document (since the XML declaration 
> is required by XML 1.1).  Thoughts?

See the above quote from the Infoset which says that:

 A document which does not specify a version number
 is considered to have version 1.0.

We did not discuss this item at the telcon.
