I wonder if we should add a method here to retrieve the
innerValidationContext. It's not part of the ValidationContext interface of
course, but currently scripts that are expecting a StandardValidationContext
(and use methods on that class that are not on the interface) would break. If
we expose the underlying context, then the scripts could be updated by checking
to see if the context is a ValidationContextAdapter, then getting the
underlying context adapter if they want it. Thoughts?
