Just when you thought RELAX NG was moribund, summarily lanced by the Sith lords of schema, it shows up in the most interesting places. This time it has appeared in the latest W3C working draft for XHTML 2.0 as a normative schema definition for the markup language. I am guessing that thanks must go to ISHIKAWA, Masayasu for this. It has also worked its way into the IETF RFC for Atom 0.8, thanks to Norm Walsh. Long live RELAX NG.
