I RDF I would suggest to make this more explicit - rather than using what
amounts to plain text, encode the information in RDF:

<dcterms:valid>
  <ical:Vevent rdf:about="http://example.com/events/myevents#term1">
    <ical:start rdf:datatype="&gdate">2004-06-02</ical:start>
    <ical:end rdf:datatype="&gdate">2004-08-04</ical:end>
  <ical:Vevent>
</dc:terms:valid>

It would be useful to have dcterms:Period defined as a subclass of
ical:Vevent - one that just represents some period, whereas events may have
places, actors, etc. But I need to check how dcterms:valid really really
defines its range.

On the other hand, I am in Shanghai now so I can do just that at the DCMI
conference shebang...

cheers
