Ah. OK. Maybe I should fix that.

It does say...

see also:
  RDF Calendar Workspace
  http://www.w3.org/2002/12/cal/

... but maybe that's too indirect.

Interesting idea.

As long as you're using code from 2000/10/swap, you might want
to try cwm's SPARQL support.

"Cwm can now run as a SPARQL server. This includes:
...
      * cwm --sparql=, which behaves like --query="
http://www.w3.org/2000/10/swap/doc/changes.html

Also, I think that query will make a separate cal:Vcalendar
bnode for each result. I doubt that's what you want. I think
maybe mozilla's calendar supports that, but Apple iCal seems
to throw away everying after the 1st BEGIN:VCALENDAR.

You might try something like...

  CONSTRUCT {<#c1> a cal:Vcalendar; cal:component [a cal:Vtodo;
  ...
