No, Matroska makes binary XML the entire container transport mechanism
(at least, that's the way your description reads).  He's talking about
an XML logical stream type, which is the way Ogg will approach it.

We've been looking at XML or a subset like RDF for at least four years
now.  Every time someone gets seriously into the planning stage, they
lose ability or interest in continuing and walk away. This is not a
new idea; no one has yet demonstrated the staying power to actually
make it happen.

If you're not allergic to work, this is a very large, very important
task (arbitrary, streamed metadata).  It's not as large as it used to
be; there are now a few different tried and true
standards/implementations ot choose from.  At worst, you'll likely
have to oversee adapting a suggested schema and maintaining the Ogg
stream mapping def for it.
