I's rather stay away from Connolly's explicitly stated point, although I'll say: I think he's being quite undiscriminating. A minimum of optional features might have worked as a design dgoal of XML, but it would not have worked as a design goal for DOM. The obvious reason is that these two specs are very different beasts. For some beasts conformance levels are a net gain. For some, they're a net loss. Should anyone even have to state such an obvious matter? And let's not forget that in spite of its design goal, XML has at least one major conformance level. Hasn't killed XML yet. But migrating to what Connolly said to its possible relevance to the XPath 2.0 problem. Dan is heavily invested in the W3C, so I'll just put it this way: if XPath comes out with the sort of complex PSVI support that it currently sports, without these being profiled into some conformance level, XPath 2.0 will be a failure, and the W3C will have wasted huge amounts of resources having developed it. This is the simple fact. Never mind the theoretic evil of conformance levels. -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://4Suite.org http://fourthought.com Track chair, XML/Web Services One Boston: http://www.xmlconference.com/ Basic XML and RDF techniques for knowledge management, Part 7 - http://www-106.ibm.com/developerworks/xml/library/x-think12.html Keeping pace with James Clark - http://www-106.ibm.com/developerworks/xml/libra ry/x-jclark.html Python and XML development using 4Suite, Part 3: 4RDF - http://www-105.ibm.com/developerworks/education.nsf/xml-onlinecourse-bytitle/8A 1EA5A2CF4621C386256BBB006F4CEC
