It's a bug and it still exists in Xerces 2.7.1. While executing Document.normalizeDocument(), the DOM normalizer receives default attributes from the validator and adds them to the DOM using an internal insert method which doesn't notify event listeners about the insert. There appear to be some other problems with this method, including the one you reported in your next post to the list [1]. Will take a look at it when I find some time.
If you move up to Xerces 2.7, you do have another option. Xerces now implements the JAXP 1.3 Validation API [2]. If you validate a DOM using a JAXP Validator (specifying both the source and the result as the same node) your event listener will receive events for the defaulted attributes. Thanks.
