BinXML is a product of the company Robin works for, isn't it?

No, no, relax; in the scheme I suggested, it uses the type information as 
*advisory* data on how to encode stuff. It could ignore it all and just put 
everything in as strings. This is what people refer to as a "Schema-aware 
compressor".

There are many possible encoding schemes for the kinds of trees XML encodes, 
with different pros and cons. One of them is documented by the W3C. Another 
is documented by the ISO and ITU. Another is a (proprietary?) product of a 
company. Another is in MPEG but IIRC is encumbered by some patent somewhere. 
And they are all useful for different situations.
