xmlhack: Modularization of XHTML hops to Candidate Recommendation

The W3C released the Candidate Recommendation of Modularization of XHTML on 20 October, a mere 16 days after the release of the previous Working Draft.

Modularization of XHTML has proceeded in fits and starts, with a nine-month gap between the publication of the Last Call Working Draft and the 4 October draft, which was briefly published as a 3 October Candidate Recommendation.

Differences between this draft and the 4 October draft are relatively minor, including the conversion of relative URI references used for DTDs to absolute URIs, and the addition of some conformance language specifying that the rules described for DTDs in this document may apply to other possibilities.
