Thanks for raising this. It's a fair question to ask. I have some
sympathy with Martin Hepp's view, that we may be better off
materialising multiple event descriptions, rather than assuming smart
clients. Robert Kost suggested ISO-8601 however many tools use
restricted subsets of that standard, so I'm not sure that would be a
strong candidate.

I have summarised discussion so far in our Wiki at
http://www.w3.org/wiki/WebSchemas/RepeatingEvents and opened an issue
tracker on this at https://www.w3.org/2011/webschema/track/issues/11
since whatever we conclude should be documented.

There is also some earlier work on representing iCalendar in RDF, see
http://www.w3.org/wiki/RdfCalendarDocumentation and
http://www.w3.org/TR/rdfcal/ as well  as the fairly widely adopted
hcalendar work from the Microformats community,
http://microformats.org/wiki/hcalendar  (I don't see the word 'repeat'
in that last link but I've not yet dug very deeply).

cheers,

Dan
