Hi Henry,

It's not because your car can drive 200 km/h that you must go that fast  :-)

I would rather say that Relax NG enables you to write schemas for which 
reliable type assertions cannot be made (while W3C XML Schema forbids 
any tiny little step in this direction).

But a schema designer can choose to use only "deterministic" patterns 
for which a Relax NG engine can provide reliable type assertions if this 
is important for her or him.

See you in San Diego.
