Section 3.4 says "When neither object to be compared is a node-set and
the operator is <=, <, >= or >, then the objects are compared by
converting both operands to numbers and comparing the numbers according
to IEEE 754.
False <= True, because number(false()) = 0 and number(true()) = 1.
Suggestions as to how XPath 1.0 could have been improved are somewhat
academic at this point...
