The TAG has recently given some attention telcons to the question of 
Binary XML and to the conclusions of the XML Binary Characterization 
Working Group [1].  I've recently become aware of an analysis by Andrew 
Layman and Don Box that may be of interest [2].  I believe their work 
supports the following conclusions:

* An alternative to binary XML, Andrew and Don show that a LISP-like text 
syntax "(...) may optimize better than the existing "<...>" approach.

* As some of us stated repeatedly, detailed experimental measurements and 
even formal performance models are essential to justifying any particular 
approach to optimization. 
I suggest we consider these important results in any future discussions.
