ok, you got me....selfishly I was thinking 'all my perl scripts wouldnt 
work, if it had to consume a new definition of well formed xml'

There is still much adoption to occur with XML; lets not contemplate 
scratching the 'itch' of changing or adding to XML until we have 
unlimited storage, network bandwith, and processing power!

no doubt saxon would be the first to elegantly implement such a change, 
though I am still laughing at  the 'it *only* changes the lexical 
representation'....bit and how much work I would have to do and fix my 
perl/bash scripts.

I would weakly argue that lexical representation and data model are 
always interelated the moment the come into existence; if not only for 
the indirect inferences that programmers make (and depend upon) betwixt 
the two (as codified in my rubbish perl scripts).

As a sidenote; there is a 'chicken and egg' of what comes first with 
such things, as we are trying to do something useful in computing we 
tend to find a bit of one or the other already in/formally defined in 
existence e.g. the lexical represtentation or data model. In the case of 
XML its probable that it was a relatively clean slate (though heavily 
informed by experiences with SGML, html, lisp etc...etc...) and the spec 
itself defines good seperation between the two; though I would bet large 
sums against such an event occuring (going to ladbrokes.com now).
