make-validator (schema &optional handler)
a SAX handler
This function creates a validation handler for schema, to be used for validation of a document against that schema.
The validation handler processes SAX events and can be used with any function generating such events, in particular with cxml:parse-file.
Events will be passed on unchanged to handler.
This validator does not perform DTD compatibility processing. (Specify a DTD compatibility handler as the second argument to this function instead.)
