    This parameter is a flag for the type of XCAP servers used. If the XCAP
    server is integrated with Kamailio presence_xml module and access the
    same database tables directly, like the embedded XCAP server
-   implemented in xcap_server module, the parameter should be set to a
-   positive value. Apart from updating in xcap table, if the integrated
-   server is not running on the same Kamailio instance, it must send an
-   RPC command presence.refreshWatchers [pres_uri] [event] when a user
-   modifies a rules document, to instruct the presence_xml module to
-   update states from the database and, if needed, send NOTIFY updates.

-   servers with HTTP requests.
