Paul --

I see that there are some changes in -36 around this text ("IANA will 
populate its registries with some or all of these values"). This isn't 
really clear enough for IANA to know what to do. Could you produce a new 
version that is explicit regarding which of these collected fields are 
published? (e.g.: "IANA will populate its registries with the parameter 
name, the parameter type, and the document reference.")

Thanks.
