The recipient of the REFER method [1] creates an implicit 
subscription to the 'refer' event. This subscription causes the REFER 
recipient to send NOTIFY messages to the sender informing him of the 
progress of the REFER. This memo provides for the requirements and 
one potential mechanism to suppress the creation of this implicit 
subscription, via an option tag - 'norefersub'. This gives the agent 
sending the REFER control over the creation of the subscription, 
while being backwards compatible with [1].

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	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.
