A viable solution will be to use Gentoo-esque "USE flags". Tag
(sub)packages with what feature they provide -- e.g. MP3, DVD playback
-- and also the package(s) for which they enable this functionality.

Thus xine-lib-moles will have this:

<functionality name="mp3" for="xine-lib" />

If xine-lib is installed on your computer, and you ask for MP3
support, it will install xine-lib-moles; if not, it won't. Likewise,
if you have enabled MP3 support and then later install xine-lib, it
should pull in xine-lib-moles as well.

Thoughts? This could almost be fitted into Provides: / Requires:, but
I don't think it actually can.
