Actually the URI does exist, as it is the RLS URI defined by sipsimple for your account and stored in the XCAP documents. Maybe your SIP server is not configured to use RLS?
As for the syntax, it's not defined by any rfc. It's just a convention we made in sipsimple. In the end it doesn't matter what URI we use as long as it is unique and it doesn't conflict with other users on the server.
