Xerces2-J http://apache.org/xml/features/validation/warn-on-undeclared-elemdef?

[Gerben]

I try to use
"http://apache.org/xml/features/validation/warn-on-undeclared-elemdef":

---
System.setProperty("javax.xml.parsers.SAXParserFactory",
"org.apache.xerces.jaxp.SAXParserFactoryImpl");

SAXParserFactory parserFactory = SAXParserFactory.newInstance();
SAXParser parser = parserFactory.newSAXParser();
XMLReader reader = parser.getXMLReader();


reader.getFeature("http://apache.org/xml/features/validation/warn-on-undecla
red-elemdef");
---

but an exception is thrown:

org.xml.sax.SAXNotRecognizedException:
http://apache.org/xml/features/validation/warn-on-undeclared-elemdef

other features work. Any ideas?

This is bug that was fixed (see:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=21845). I think If you
install fresh stable Xerces2-J version(2.5.0) then It's Ok!

As far as i know, i am using 2.5.0. How can i be sure?
