GeneralComparison10: a boolean expression that compares two expressions
for equals, not-equals, greater-than or less-than. This implements the operators
=, !=, <, >, etc. This version of the class implements general comparisons
in XPath 1.0 backwards compatibility mode, as defined in the Oct 2004 revision
of the specifications.
