The first sentence is correct.  Coding against XML is simpler and 
cheaper when all the tags come from one vocabulary; clearly there is a 
cost when you have to get into handler dispatching and multi-schema 
validation and so on.  I think what you're really arguing is that there 
are ways to deal with this which are both cheaper than, and just as 
general as, the namespaces mechanism.  This is a much more constructive 
argument than the "Namespaces hurt my tender sensibilities" permathread 
that's been going on around here!

If you want another approach to be perceived as a serious competitor, 
you probably need to write it up in a relatively coherent form and 
publish it somewhere on the Web.  Or has that been done?

Perhaps you need to step back a space.  Namespaces in XML claims to 
allow disambiguation of names from different vocabularies, which it 
does.  I think you're also arguing that this is the the wrong problem to 
try and solve.

Anyhow, write it all down, post it or submit it to a conference or 
something, and see whether you can start a revolution.  To improve your 
chances, identify some working software that implements your approach.
