You earlier commented on the RDF Core Last Call working drafts, particularly 
on the design of XMLLiterals.

This message concerns those comments, listed as:
http://www.w3.org/2001/sw/RDFCore/20030123-issues/#reagle-01
http://www.w3.org/2001/sw/RDFCore/20030123-issues/#reagle-02
and
also
http://lists.w3.org/Archives/Public/www-rdf-comments/2003JanMar/0434
"Confusion about wrapping of XMLLiteral"
which did not get an issue number assigned.

We have modifed the decisions reflected in our earlier reply:
http://lists.w3.org/Archives/Public/www-rdf-comments/2003AprJun/0021

While contemplating various last call issues RDF Core WG has simplified the 
design of typed literals, particularly XMLLiteral, by removing the language 
tag.

This permits addressing:
http://lists.w3.org/Archives/Public/www-rdf-comments/2003JanMar/0434
"Confusion about wrapping of XMLLiteral" by simply removing the wrapper 
altogether.

The resolution to modify the design was decided on 09th May 2003
http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2003May/0138.html
and reads:
RESOLVED: Typed literals option 4 from msg 0086

which refers to
http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2003May/0086
[[
> Option 4:
> Language tag is simply dropped from all typed literals including
> rdf:XMLLiteral
>
>

PROPOSE
  Concepts is changed to say that a literal can have either a datatype or a
language tag and not both.
  rdf:XMLLiteral datatype is changed to have the identity as its lexical
value mapping (no wrapping), with consequential change to the value space of
rdf:XMLLiteral.
  Other editors to make consequential changes.
]]
we further clarified (20th June) that "the identity" was over-simplistic, and 
the value space remains a set of exclusively canonicalized XML,
http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2003Jun/0156.html

The new text defining XML Literal can be found in the editors draft at:
http://www.w3.org/2001/sw/RDFCore/TR/WD-rdf-concepts-20030117/#section-XMLLiteral


Please note that the I18N-WG have made a comment criticizing this decision:
http://lists.w3.org/Archives/Public/w3c-rdfcore-wg/2003Jun/0023.html
which the RDF Core has not officially yet agreed a response (although we have 
spent more than an hour of telecon time on it, with still a majority opposing 
further changes). 

I will update you on any further changes (well I hope not!).

Please let us know, copying www-rdf-comments@w3.org if:
Joe:
- these changes make the previously confusing decisions acceptable
- if you find these changes address
http://lists.w3.org/Archives/Public/www-rdf-comments/2003JanMar/0434
"Confusion about wrapping of XMLLiteral"
in an acceptable fashion

Eric, WebOnt:
