This has been a (severe) concrete problem in ontologies developed at the University of Manchester. It's worth revisiting.

If this family of datatypes are going to be considered at the RDF level, then we should, by all means, synch up requirements and, well, actual specs.

I happily volunteer to work on this from the OWL side (if there's concern about labor).

Cheers,
