Please elaborate. Whats the advantage of

   ATTENDEE;X-EMAIL=abc at def.de:urn:uid:98128912

over

   ATTENDEE;X-CALSERVER-UID=98128912:mailto:abc at def.de
or
   ATTENDEE;DIR=urn:uid:98128912:mailto:abc at def.de

Thats the core of my claim of 'no good reason'. Your requirements can  
be met w/o breaking anything existing. (if this does break with some  
client, please tell us which)


Further, as I said, there is no way for a client to resolve a UID to  
some contact record. You talk about a REPORT to resolve UIDs, I  
suppose this might be OK. Whats this REPORT?

BTW1: using properties for lastname/firstname etc is rather useless,  
since properties are not covered by etags, hence uncachable.
BTW2: a vCard URL would be nice. (doesn't even have to be CardDAV,  
plain URL pointing to a vCard would be fine, similiar to FBURL)

Well, yes, I also thought that we might want to standardize a UID  
parameter to avoid an X-CALSERVER-UID. But then, this is basically  
what DIR already provides.

Thanks,
