Draft draft-ietf-sipping-uri-list-subscribe-03.txt enables subscribing to a list of users.
In many cases the list of users changes quite fast and sending the whole modified list again may be quite heavy.

I think that it will be quite helpful to add very simple add/remove operators to the URI list of subscribe in order to
enable fast change of the URI list.

For example if the initial body of the subscribe was:

<?xml version="1.0" encoding="UTF-8"?>
<resource-lists xmlns="urn:ietf:params:xml:ns:resource-lists"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<list>
<entry uri="sip:bill@example.com" />
<entry uri="sip:joe@example.org" />
<entry uri="sip:ted@example.net" />
</list>
</resource-lists>

If we want to add Alice and remove Bill the resubscribe will look like (more or less):

<?xml version="1.0" encoding="UTF-8"?>
<resource-lists xmlns="urn:ietf:params:xml:ns:resource-lists"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<list>
<<REM> entry uri="sip:bill@example.com" />
<<ADD> entry uri="sip:alice@example.org" />
</list>
</resource-lists>
