We don't use LOM, but something quite like it. We have a serializer
that we've optimised to death, it wouldn't be hard to adapt it for
LOM, or insert linebreaks after attributes. The code starts here:
http://hg.prosody.im/trunk/file/4621c92d2368/util/stanza.lua#l178 and
runs until line 218.

The rest of that module is about creating and manipulating snippets of
XML, some documentation at
http://prosody.im/doc/developers/util/stanza .
