Validation is currently a Xerces issue; take this question back to that
list. (There ways to persuade Xerces to "revalidate" a document. They
involve working with the XNI APIs and are moderately ugly. Unless you
really want to deal with that level of detail and nonportability, I would
suggest you serialize to XML syntax and reparse. They may have better
suggestions.)
XSLT 2.0 *MAY* introduce the concept of validation of selected subtrees.
(There's been debate over whether that feature belongs in XSLT, XQuery,
both or neither.) If and when that's accepted as part of the spec, Xalan
will have to learn how to work with Xerces to do this. There is a
prototype of that code on the xslt20 branch. It's moderately ugly, highly
experimental, hasn't been tested in a very long time... basically, I don't
really recommend it; caveat hackitor. Its greatest value may be as a code
example if you really do need to attempt this.
