mod_pubsub_subscription/mod_pubsub_subscription.lua @ 4523:6e20e6bf96f0
mod_rest: Add XEP-0066 to mapping schema (breaking from previous jsonmap)
before:
oob_url: http://example.com/

oob:
url: http://example.com/
desc: optional description
Deals with the fact that the name and namespace differs based on whether
it's in an iq or message stanza, unlike oob_url
