[SIP Beyond VoIP] escaped sip uris in xcap rls documents

[Juha Heinanen]

i "solved" the problem described below by adding a line in
xcaplib/client.py XCAPClientBase _put function that un-escapes : and @
chars:

    def _put(self, application, resource, node=None, etag=None, etagnot=None, headers=None, **kwargs):
        resource = resource.replace("%3A", ":").replace("%40", "@")

most likely that is not the correct way to solve the issue.  better
solutions are welcome.
