He is not talking about arbitrary XML, he has a DTD. The infoset of the file may 
be more predictable (and thus compressable) than the XML he showed us.

People use XML because they like the tools and the galaxy of related 
specifications. He could indeed define an ad hoc binary format for his needs, 
but I see the fact that that is precisely what many are doing as a cause for 
concern, especially as it's not done only in closed systems.
