I'd prefer not to. Adding examples for more then the absolute trivial 
things (like booleans or dates) is likely to open the proverbial can of 
worms, because people have different tastes about types and optimal 
serializations. So in doubt I'd even prefer to *remove* the current 
appendix (as I'm not convinced that this is a good serialization format 
given it's based on an outdated SOAP spec; it just happens to be what we 
*do* implement right now).

Again, I'd prefer not to. An array is an array; not a set.

Well, that's the whole point of having an array.

I understand that you are particulary interested in this data type 
because you'll need it. It seems to me that the best strategy for you is 
to define that type in a separate document (possibly standalone or 
caldav), and let the property types spec stay out of this business.
