key ambiguity check

I did a casual experiment for the key ambiguity check with the DocBook
schema.

Maybe it was because of my poor implementation, but I recorded that
almost 80% of the parsing time is spent to enforce the key ambiguity
check. That is, enforcing this check makes schema parsing 5 times slower.


I'm curious how it is like in Jing.
