I'd be keen!
BiM may be a stream-focussed protocol with no seekability, is my main
worry.
The ASN.1 project seems to be based around the idea of using a schema to
encode data with no self-description information in it, and requiring the
same schema at the other to make sense of it. Although there are
applications for this, I feel a representation that you could round trip
XML through without reference to any schemas or DTDs will be more
generally useful and will not suffer from not being self-describing.
We can probably suggested an ASN.1 based representation for a
self-describing XML representation as a logical extension to the ITU's
work, and get them to accept it as part of the same recommendation... not
sure about the politics, though.

Definitely, otherwise we raise barriers to adoption...

Mmmm; I have a solution for those two requireements :-)
