[Iptel] [Fwd: I-D ACTION:draft-ietf-iptel-rfc2806bis-06.txt]

[Jonathan Rosenberg <[e-mail]>]

Folks,

You may have noticed that the IANA registry has been removed from -06.

Generally speaking, the purpose of IANA registries is to avoid conflicts 
that may arise if two different groups/users select the same name for a 
parameter. This is clearly an issue for things like BGP AS numbers, 
which are actually allocated by IANA. For parameters in protocol 
specifications, problems only arise when different specifications 
accidentally use the same name. This is less likely to happen, and its 
likelihood depends on how much extensibility is expeted for the 
protocol. For SIP headers, we deemed it useful because of the large 
number of extensions that were anticipated. However, I do not expect a 
lot of extensions to the tel URI, and thus the IANA registry doesnt add 
a lot of value. Indeed, it is likely to slow up publication of 2806bis 
and add additional load on an already-busy IANA.

Thus, I think it makes sense to drop the iana registry.

Thanks,
Jonathan R.

NOTE:	The mail server at ietf.org can return the document in

	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
