Dependency on XSD 1.1 -- possible compromise

Sorry for the long email, but this is an important matter, and I  
wanted to provide complete information. Please read carefully and let  
me know if you have any comments.

And thanks to everyone whose hard work has made progress possible.

After a careful examination of the dependencies and checking the  
stability of the relevant parts of the XSD 1.1 spec it has been  
suggested that we could go forward to PR under the following conditions:

1) Normative references to XML Schema Datatypes be changed to  
normatively refer to XSD 1.0 as updated by XSD 1.1 when it becomes a  
recommendation, with a pointer to the existing XSD 1.1 CR as a  
nonnormative indication of the expected content of said update. The  
proposed text for the reference is:

[XML Schema Datatypes]
    W3C XML Schema Part 2: Datatypes Second Edition, Paul V. Biron and
     Ashok Malhotra, eds. W3C Recommendation 28 October 2004,
     http://www.w3.org/TR/xmlschema-2/. It is expected that in a future
     revision this reference will be replaced with a normative reference
     to a W3C Recommendation of XML Schema Definition Language (XSD) 1.1
     Part 2: Datatypes. The (non-normative) version of this document
     available at publication time is the 30 April 2009 Candidate
     Recommendation.


2) In Conformance we say that the additional features offered by XSD  
1.1 are considered optional at this time, but that we expect XSD 1.1  
to become a Recommendation and that references to it will then be  
considered normative. The proposed text is as follows:

     As of the publication of this document, version 1.1 is not yet a  
W3C
     Recommendation.  Both the OWL Working Group and the XML Schema  
Working
     Group are confident that there will be only minor changes before it
     becomes a W3C Recommendation. In order to take advantage of the
     anticipated corrections and new features sooner, while also  
providing
     stability in case the specification does not advance as expected,
     conformance to OWL 2 as it relates to XML Schema Datatypes is  
defined
     as follows:

      - If XSD 1.1 becomes a W3C Recommendation, all references in  
OWL 2 to
         XML Schema Datatype features will be normative references to  
the
	   1.1 Recommendation.

     - Until that time, references in OWL 2 to XML Schema Datatype
        features operate as follows:

     a) If XSD 1.0 defines the features, then the reference is normative
     to the 1.0 definition.  b) Otherwise, the feature is optional in  
OWL
     2 and the reference is informative only.

     This "change in normative reference" is effective as of the
     publication of XSD 1.1 as a W3C Recommendation.  However, W3C  
expects
     to publish a new edition of OWL 2 once XSD 1.1 becomes a
     Recommendation to update the reference explicitly.


3) The OWL WG would remain open, but "dormant", pending the  
transition of XSD 1.1 to Recommendation. At this point we would  
briefly emerge from our dormant state in order to change the  
documents to normatively reference XSD 1.1 and to remove the above  
text from Conformance.
