--- FIXME: XEP-0227 supports XInclude but luaexpat does not
---
--- XEP-227 elements and their current level of support:
--- Hosts : supported
--- Users : supported
--- Rosters : supported, needs testing
--- Offline Messages : supported, needs testing
--- Private XML Storage : supported, needs testing
--- vCards : supported, needs testing
--- Privacy Lists: UNSUPPORTED
--- http://xmpp.org/extensions/xep-0227.html#privacy-lists
--- mod_privacy uses dm.load(username, host, "privacy"); and stores stanzas 1:1
--- Incoming Subscription Requests : supported
