This suggestion falls well short of an optimal
solution.  The Vorbis docs even state "arbitrary
metadata belongs in a separate logical
bitstream (usually an XML stream type) that
provides greater structure and machine
parseability".

The optimal solution is described at:
https://wiki.xiph.org/XMLEmbedding

However, this draft hasn't been touched since
2007.

The other problem was that adding a separate
XML stream to an Ogg container would break
many existing players.  Presumably, since the
introduction of Ogg Skeleton, that is not such a
problem now.
