And does. A specification I worked on recently uses SOAP, and mandates the HTTP 
binding with content-negotiation (I wish the official SOAP HTTP binding would do 
that as well...). They wished to transmit binary infosets optionally, and 
mandated XML for interoperability. This is not a closed system, on the contrary 
it's a very open one. Selecting between either option is a trivial matter of 
setting the correct Accept-Encoding/Content-Encoding, and it has shown to work 
very smoothly.

That could very well happen eventually, but unfortunately, barring a revolution 
it won't be the case before at least a few years.

2003 is to see several consortia start ratifying binary infosets, some of them 
might end up being home-grown. This wasn't obvious to me before I started 
delving into the topic, but I'm seriously concerned that chaos isn't very far away.

It's not the impression I get from mobile, broadcast, and embedded orientated 
developers either.
