In Section 8, you recommend using the HTTP URIs of the RFCs as XML 
namespace names. This is potentially problematic (what happens when ther 
are superseded?). I'd suggest XML namespace URIs in the 
urn:ietf:params:xml:ns tree (RFC 3920 is a recent spec that uses these).

In Section 9, your media types are off -- "application/calendar+xml" is 
more correct. http://www.xmpp.org/specs/rfc3923.html#iana has an example 
of a recent content-type registration of this kind. When the time comes, 
don't forget to run your definition by the friendly folks on the 
ietf-types list: http://www.alvestrand.no/mailman/listinfo/ietf-types

In Section 11.1 you define a DTD. That's so old-fashioned -- all the 
cool kids are using XML schema these days. ;-)

That's about as far as I got. It'll be great to have an XML format for 
calendar objects!

P.S. Given some of the layout oddities, it seems that perhaps you did 
not use the XML RFC format; http://xml.resource.org/ tells you how and 
it is highly recommended!
