Norman Walsh wrote about a simplified version of XML. The draft is called: Extensible Markup Language (XML) 1.1 Kernel. DOCTYPEs are irrelevant and would now cause a non well-formed error to be raised. Bye bye entities not part of the five known ones. Bye bye validating XHTML pages. I personally think this is good move forward to get rid of all that legacy stuff. No browser parses a DOCTYPE when it encounters one in an XML document. MSHTML used to do it, but stopped doing it by default in MSXML6 according to Sjoerd. As browsers have no quirks versus standards mode in XML they are not needed for that purpose and are better dropped. Now the only thing that is left is to merge that with the namespaces specification and get it all out as a single draft. Yay for when that happens.
