Yes, maintenance on crimson continues and bug fixes are very much
appreciated.  Thanks!

Thanks for the short test case.  I've checked in a fix for this.

BTW, the preferred way to create a DOM document is to use the JAXP 1.1
APIs and not internal parser APIs like XmlDocument().  Here is an

DocumentBuilderFactory dbf = new DocumentBuilderFactory();
dbf.setNamespaceAware(true);  // needed b/c default value is false
DocumentBuilder db = dbf.newDocumentBuilder();
DOMImplementation di = db.getDOMImplementation();  // W3C DOM Impl
DocumentType dt = di.createDocumentType("pref:root", pubID, sysId);
Document doc = createDocument("http://someuri", "pref:root", dt);

Substitute appropriate values of the root node qname "pref:root" and
uri.  This will allow you to move your app easily to another parser such
as Xerces 2.
