If by extensibility you mean the ability to create your own language, yes.

If you also mean the ability to include new information in an existing

And the ability to extend (and evolve) the XML specification itself is 
still to be seen...

No, but if you change the structure even slightly, how many of your 
applications will be affected?

Sorry I haven't been clear!
