Complementing Cecil, you misread the RFC. Typical XMPP URIs don't have
an authority component, so your example should look like:
xmpp:guest at example.com/Home
This is because the authority component describes the service to connect
to, to get to a certain resource. In the XMPP case, you usually use your
own server to connect to other JIDs, so the authority component can be
empty (the default being your own server, with your own account).
If you wanted to have a specific service to connect to before accessing
the resource, you'd do:
This means: open an XMPP connection to the server at example.org using
account 'test', and then use that connection to access the JID
guest at example.com/Home. This is explained in section 2.3.
In this example, the path component is:
guest at example.com
Not that XMPP URIs don't have path segments like other (hierarchical)
URI schemes, most notably HTTP. The fact that we have a '/' character in
there is an historical artefact carried over from JIDs.

No. An XMPP URI /is/ a real URI, no mapping required.

Neither, as I explained above.
