Various XMPP extensions, such as &xep0166;, require additional support from clients, advertised in presence via &xep0115;, or require that IQ stanzas are sent to a particular resource. For instance, Jingle calls can be made only by sending an IQ to a particular resource. However, two parties who wish to communicate do not always shared presence information and therefore cannot use entity capabilities to determine the correct resource (full JID) for communication. Indeed, one of the parties might not even use XMPP: e.g., a remote user on the other side of a gateway to a network based on the Session Initiation Protocol (SIP; &rfc3261;) or to the Public Switched Telephone Network (PSTN). It would be helpful if a user could make a call through such a gateway by typing the SIP URI or telephone number of an arbitrary contact, without first exchanging presence.
-This document defines an XML protocol extension to request that enables two parties to temporarily share presence with each other through an intentional presence leak.

Note: This protocol has already been implemented using an XML namespace of "http://telepathy.freedesktop.org/xmpp/protocol/decloak" but the ®ISTRAR; was requested to issue the XMPP URN "urn:xmpp:temppres:0" upon publication of this proposal in the &xep0001; series.
