Re: [Gen-art] Genart last call review of draft-gellens-lost-validation-05

Hi Randy,

Section 3 of the document defines the operations that one must perform 
in order to use the tag. It explains how to go beyond what 5222 provides 
by defining which order to look up the servers and what to do depending 
on the results received. It changes the discovery procedure defined in 
5222. The fact that it is backwards compatible and doesn't break 5222 
implementations is good, but it doesn't make it any less a protocol. 
Indeed, if it is an "optimization" of an existing protocol, that makes 
it a protocol. I can't see any other way of describing section 3.
