XML's strengths are interoperability and toolability. A binary format
would break both, for negligable gains -- a good XML parser can read
XML at nearly the same speed that one could deserialize from a binary

If you're worried about verbosity XML compresses wonderfully when put
through any of the standard adaptive algorithms (zip and its cousins),
and decompressing those doesn't add much overhead.

While there are certainly things a binary format would be better for,
that tends to be a huge mixed bag of goals, many of which directly
conflict in the requirements they would want to impose on the data

If you want a binary format, by all means invent one that suits your
needs, and import/export it to XML. But don't expect it to be
interoperable. Remember, the whole reason XML took off was that binary
formats WEREN'T easily interoperable, even those explicitly intended
to be so.
