XEP-0066: Out-of-Band Data
Out-of-Band Data is a basic method for transferring files between
XMPP agents. The URL of the resource in question is sent to the receiving
entity, which then downloads the resource before responding to the OOB
request. OOB is also used as a generic means to transmit URLs in other
stanzas to indicate where to find additional information.
Also see <http://www.xmpp.org/extensions/xep-0066.html>.

oob_transfer -- Raised when a request to download a resource
has been received.
