If you have a pretty good idea of the set of schemas that will be needed before reading the instance documents, you could preparse those schemas into a GrammarPool associated with the instance document parser. That way, most or all of the documents could be validated as they are read (the first time). As a backup, normalizeDocument could be used on the remaining ones.
