Thanks for the pointer, Bjoern.

I's rather stay away from Connolly's explicitly stated point, although I'll 

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.
