Right. I think that a provider will tend to control the key change than the 
subscriber. Because the subscriber is being given access to a service. But yes, 
in theory, either side could change where maybe the map-server is using two 
key-ids because one xTR wanted to change their key and other xTRs did not. For 
whatever reason.

I’ll draft up text and send to the list.
