David Orchard wrote If we have "blown" the issue of compatible evolution of a URI, then I think we should figure out the right way forward in general rather than hack something architecturally inconsistent. We had the same issue for MathML. MathML 2 (2nd Ed) does re-use the "short" URI for MathML 2 (1st Ed) although that is a different short uri from MathML 1. At the suggestion of the W3C Publication team we made this explicit in the formal frontmatter section of the MathML 2 Rec, which states This version: http://www.w3.org/TR/2003/REC-MathML2-20031021/ Latest MathML 2 version: http://www.w3.org/TR/MathML2/ Latest MathML Recommendation: http://www.w3.org/TR/MathML/ In ther words all three of those URI currently give you the same document, but http://www.w3.org/TR/2003/REC-MathML2-20031021/ will always give you MathML 2.0 2nd ed. http://www.w3.org/TR/MathML2/ Will give you MathML 2.1 or MathML 2.0 3rd edition should there ever be such a thing. http://www.w3.org/TR/MathML/ will give you MathML 3 if there will ever be such a thing. The MathML version of xmlspec dtd and stylesheets have some support for this frontmatter style, David ________________________________________________________________________ This e-mail has been scanned for all viruses by Star Internet.
