Scenario :
Loading a rls-services XML file to [email protected] (XCAP HTTP PUT) :
```xml
<?xml version="1.0" encoding="UTF-8"?>
<rls-services>
<service uri="sip:[email protected]">
<list name="points">
<entry uri="sip:[email protected]">
<display-name>Point 1</display-name>
</entry>
<entry uri="sip:[email protected]">
<display-name>Point 2</display-name>
</entry>
<entry uri="sip:[email protected]">
<display-name>Point 3</display-name>
</entry>
</list>
<packages>
<package>presence</package>
</packages>
</service>
</rls-services>
```
[email protected] -> subscribes to event presence on -> [email protected]
[email protected] -> subscribes to event presence on -> [email protected]
[email protected] -> subscribes to event presence on -> [email protected]
Waiting some time (10~20 seconds, approx rls, waitn_time option)...
[email protected] -> subscribes to event presence on -> [email protected]
[email protected] -> subscribes to RLS event presence.winfo for the first time
on -> [email protected]
Kamailio sends only partial state as mentioned in "fullState="false"" and
"state="partial"" and only for user dave (last one subscribed) with version "5"
:

If I am reading well RFC 4662 Section 4.5
(https://tools.ietf.org/html/rfc4662#section-4.5) Kamailio should send a full
state NOTIFY for initial RLS subscribes and then it can send a partial state
for updates.
I think we lose information here, but if a re-subscribe is performed I get a
full NOTIFY, which is my current "workaround" :
1 - Initial subscribe
2 - If full state -> OK
3 - If partial state -> re-subscribe
```xml
