Isn't this where the binary XML format is supposed to shine?
It seems to me that the binary XML format is often neglected and people 
just think of the textual format.
Binary XML was supposed to offer the advantage of not needing to create 
a new parser for each new format whilst still retaining a nice and 
compact format for the wire.

It seems to me that it's a smart approach in principle that leaves the 
possibilty of easily created clients and sniffers.
