"IMS has been using implicit registration since 2002. No one has identified any interoperability issues in the fora I attend with this.

So I would like some specifics as to what interoperability issues the use of implicit registration is understood to cause, because it does not seem to be in the drafts."

The draft attempts to describe interop issues encountered with the 3GPP, ETSI, Cablelabs and "adhoc" models. 

During the meeting, you described some problems in the draft's characterization of IMS implicit registration.   It might be helpful if you could describe in more detail on the list what a more correct characterization would be.
