Nits/editorial comments:
Generic comment about SIP Header Field Parameters registry: For the
uninitiated this registry is rather opaque. Some parameters, such as
the Call-Info purpose parameter for which an extra value is defined
here, have predefined values. However the predefined values themselves
are not in the registry and just giving a whole RFC reference for places
where values are defined is not very helpful. For example, in the case
of Call-Info, the initial predefined values of purpose are buried in the
Call-Info rule in the ABNF in Section 25.1 of RFC 3261; also, Section
20.9 describes the predefined values (such as "icon") as 'parameters'
rather than values of 'purpose'. It would probably be helpful to either
improve the references in the registry table or actaully quote the
possible predefined values in the table.
