When I first wrote the ValidationContext interface, there were methods
only enough to implement W3C XML Schema Part 2. Specifically,
prefix<->URI mapping and the unparsed entities. Because W3C XML Schema
datatype library seems to be the minimum requirement for any non-trivial
RELAX NG validators.

After that, notation declaration information is added by the suggestion
from James.

I'm happy to add them especially if they are optional. But I'd like to
wait to hear from James.



Or it might be even better to have something like:

Object getProperty( String propertyName );

... instead of adding methods for every possible information.
