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

- DTB
- Raised by:
- Christopher Welty

- 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. - Related Actions Items:
- No related actions
- Related emails:
- ACTION-726 completed and new issues arising from that. (from axel.polleres@deri.org on 2009-04-08)
Related notes:
At F2F13 the WG resolved not to have these general comparison predicates.
