There is one more change to the RFC due to the duplicate of message types:

section 3.4.5: "CLIENT_WHO", "CLIENT_WHO_NONEXIST" and 
"CLIENT_WHO_EXIST" are the same as:

section 3.6.1.3.1: "CLIENT_USER_IN_COORDINATOR",
"CLIENT_USER_IN_COORDINATOR_YES"
and "CLIENT_USER_IN_COORDINATOR_NO".

The following attached RFC has the changes: I removed the message formats i
n
section 3.4.5, and made references to section 3.6.1.3.1 there.
