ISSUE-96: General literal-< (etc.) predicate that covers < tests for all literals

Infix comparators

General literal-< (etc.) predicate that covers < tests for all literals

Description:
At the 31-Mar-09 telecon, ISSUE-67 was discussed and Sandro observed that, for < to be a datatype-independent infix operator in the presentation syntax, there needs to be a "literal-<" predicate (as well as >, <=, >=) that subsumes the behavior of the datatype specific predicates. For strings, this would wrap fn:compare, for numbers it would wrap numeric-<, and for incomparable types would probably be undefined.

There was mild support for the notion at the telecon, provided someone was willing to do the work to specify it.

At F2F13 the WG resolved not to have these general comparison predicates.
