XPath 1.0 Section 3.4


  "When neither object to be compared is a node-set and the
   operator is <=, <, >= or >, then the objects are compared
   by converting both objects to numbers and comparing the
   numbers according to IEEE 754."

And "2004-11-15" is not a number, so the cast to a number results in NaN ... which, BTW, doesn't compare true in any comparison with anything, including itself.

I hope this helps.
