a litte miss understanding here. I was talking about a method in the IDL
that allows the "pilot" to ask which IDs do (still?) exist.
the IDs would be saved in the vcard/cal file with the item it belongs to.
the UID property should provide this functionality.

what would also be needed or would at least be helpfull is a second method
 to retrieve specific items based on their ID.

the REV attribute is optional so other implementations do not have to support 
it. I do not see why one should not use it. (but what do I have to say)
