* instances: while dtd validator needs to be able to inject namespace
* declarations based on attribute default values, it should not have to
* know too much about element stack implementation, and vice versa.
* As a result, this interface defines API input element stack calls
* on the dtd validator instance. Validator instance then refers to the
* input element stack base class to do callbacks if and as necessary.
