As Alaric said, it solves the size problem, but that's just about it. Depending 
on the platform it may worsen the speed problem. Here are your typical 
requirements for a binary infosets format (they are met by very few of the 
available options):

- size
- speed (parsing time)
- streaming (the ability to send the document in independent, yet well-formed as
   per the binary format, fragments. Those are possibly sent in an order that
   does not match that of the document. This ties in strongly with XML Fragments
   and XML Packaging)
- random access (being able to skip straight to the portion of the document you
   want, without having to parse it all)

In addition to that you might want things like backward/forward compatibility 
accross schema changes.
