That's my problem with this whole discussion. We have defined a general 
connection data capability, and now we don't want it to be able to 
express anything beyond "PSTN" - exactly why did we do this again and 
what was it the WG agreed to when taking this on as a WG item ?

Also, if you explicitly prevent the ABNF from supporting IP-addresses, 
then you must be listing the values that actually are supported and 
hence we've further lost generality in how we define this and general 
alignment with the SDP structure where we register supported values 
separately. I'm really not in favor of any of that.
