None of the above.  REXML should not do validation.  It should, perhaps,
have a means for hooking one or more external validation processors, be it
via DTD, W3C XML Schema, Schematron, XML-Prover, RELAX-NG, regular
expressions, what have you.  Maybe.

Maybe it should pass back the results of validation, and perhaps have a
means for updating the REXML document based on post-validation processing
(e.g., default attributes & values provided by the PSVI ).

Validation and document manipulation are two different tasks that should be
handled separately, with an option to chain the tasks, or piped the results
of one into the other.

On a side note, prior discussion of Ruby & XML seemed to emphasize the Ruby
Way, not (necessarily) the W3C way, to process XML.  What's the Ruby Way of
validating XML?  Why worry about W3C XML schemas if there's no W3C XML DOM?
