<ALEX> Why should we bring it into YP?  We basically don't use the term there.  We use "update record" (which we do define).  </ALEX>

<ALEX> The separation makes sense and I think is something we always had in mind.  I am not clear what is needed.  We currently have "event record", which is distinguished from the "event" itself, and the "notification message", in addition to "event stream".  (We could rename "notification message" to "event notification message", which woudl become rather lengthy; we did not call it "event message" since there might be notification messages that notify of updates, which are different from events.)  
In short, I am not convinced that any changes are needed; I do think we have captured the right terms; but of course if you would like to see alternative definition text please make a suggestion.
