Yes, this is the best solution.

The "ASAP Transport Parameter" should be an optional SCTP Transport Parameter, 
to be appended to the end of the "Pool Element Parameter" in the common 
parameters draft. For ASAP (Registration), there should be no such parameter 
(the home NS has to find out the peer addresses anyway, therefore the NS 
itself can fill this information into the namespace). For ENRP 
(PeerNameUpdate and PeerNameTableResponse), this parameter has to be 
mandatory.

Best regards
