For those interested in the future of the web, the current debate about XHTML2 raging in blogland is essential reading. For my part, I’d understood that if I engineered my pages to fit the XHTML standards then a few tweaks aside that would be it, there would be the appropriate XML definitions in place and I wouldn’t need to use XHTML 2 unless it were appropriate for my documents. But that does make the naming unclear, version 2 suggests to me a suggested upgrade path rather than an alternative offered.
