At the ISO SC34 meeting in Korea, a question came up of whether there was
any scope for repackaging parts of HyTime in some more XML/XPath/XLink
friendly way. Anyone who has ideas or requirements or use cases or running
code in this area is very welcome to let an SC34 WG 1 committee person
know (e.g. Martin Bryan, Alex Brown, Lynn Price, Murata Makoto, me. I
hesitate to suggest the Microsoft and IBM representatives, because they
might be focused on other areas at the moment :-)

I don't see it myself. The poor uptake of XLink suggests there is some    
        funny dynamic at play hindering linking in general, independent of
the technical excellence of the solutions.
