What do we need XML for?
 - Styled subtitles (somehow important)
 - DASH (important for mobile)
 - XSPF, ITML and other playlist formats (somehow important)
 - lua, subsusf and rss (not really important)

VLC xml API seems to be SAX based (confirmation?) and not DOM-based,
which makes a bit of sense, I think.

libXML is huge and booring.
We should look at alternative, like expat (small but slow) or
rapidxml/tinyxml. However, I think rapidxml and tinyxml do not have a
SAX api, but only a DOM one.
ANd then do a LGPL module on it.

Best regards,
