Web Hypertext Application Technology Working Group WHATWG == HTML 5 == URL: http://www.whatwg.org/specs/web-apps/current-work/ HTML 5 defines a kaboodle of new elements and attributes, as well as some well-defined, "quirks mode" HTML parsing. Although WHATWG professes to be targeted towards web applications, many of their semantic additions would be quite useful in regular documents. Eventually, HTML Purifier will need to audit their lists and figure out what changes need to be made. This process is complicated by the fact that the WHATWG doesn't buy into W3C's modularization of XHTML 1.1: we may need to remodularize HTML 5 (probably done by section name). No sense in committing ourselves till the spec stabilizes, though. More immediately speaking though, however, is the well-defined parsing behavior that HTML 5 adds. While I have little interest in writing another DirectLex parser, other parsers like ph5p can be adapted to DOMLex to support much more flexible HTML parsing (a cool feature I've seen is how they resolve boldbothitalic). vim: et sw=4 sts=4
