The key is ensuring that the required usage is clear and unambiguous. Specifically, ISTM that a "msrps" URI together with a "dc" parameter implies that connecting to this requires use of a data channel over a DTLS association established using the address in the URI. Following up on that, a question about the example in 4.8: The path attribute includes: msrps://bob.example.com:54111/si438dsaodes;dc but the corresponding c= is: c=IN IP4 198.51.100.79 Am I to infer that =IN IP4 198.51.100.79 is the resolution of bob.example.com:54111? If so, why doesn't the c= reference bob.example.com:54111? Thanks, Paul
