This looks like the best option to me, prevents confusion and isn't that much 
more verbose.

In RDF/XML it could even be abbreviated a bit, provided there's a range 
definition for dtstart:

<Vevent>
  <dtstart rdf:parseType="Resource">
    <rdf:value 
rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2003-01-15T18:00:00</rdf:value>
    <tzid>/softwarestudio.org/Olson_20011030_5/Europe/London</tzid>
  </dtstart>
</Vevent>


Another thought: I'm not sure this is "kosher" use of datatypes, but how 
about using a timezone URI for the datatype:

<Vevent>
  <dtstart 
rdf:datatype="http://tz.example.org/softwarestudio.org/Olson_20011030_5/Europe/London"
>2003-01-15T18:00:00</dtstart>
</Vevent>

This of course leaves the XSD datetime datatype out in the cold, but perhaps 
that could be fixed with some inheritance (somens:subDatatypeOf)?


BTW, what's with the different casing of parseType and datatype?
