Michael is correct to state that W3C policy essentially prohibits changing existing documents, however it is possible to arrange that documents contain forward pointers to possible future recs. The MathML 2 "2nd edition" REC was one of the first to get to a 2nd edition of a 2nd release, and after some confusion during working draft stage as to what the "latest version" links should point to we finally came to the following scheme in consultation with the W3C web team. the document header has the links: 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/ Currently all of those point to the same thing however if we bring out mathml2 3rd edition, the second and third ones one will redirect to the new spec. if we bring out a mathml 3 then the second one will not change but the third one would then redirect to the mathml 3 spec. so although the actual visible page at http://www.w3.org/TR/2003/REC-MathML2-20031021/ will never change it will always have links to the latest versions of mathml. For this to work for Xpath and friends TR space would need to allocate "version independent" URIs cf http://www.w3.org/TR/MathML in addition to version specific URIs http://www.w3.org/TR/MathML2/ and of course dated document specific URIs http://www.w3.org/TR/2003/REC-MathML2-20031021 You can only do this for new documents though (MathML 1 doesn't have a link to MathML 2 for example) so such a scheme could only apply for xpath2 and up not xpath1 as the original poster requested.
