NIST The "setNamedItemNS(arg)" method for a NamedNodeMap should raise NO_MODIFICATION_ALLOWED_ERR DOMException if this map is readonly. Retrieve a list of "gender" elements. Get access to the THIRD element which contains an ENTITY_REFERENCE child node. Get access to the node's map. Try to add an attribute node specified by arg with method setNamedItemNS(arg). This should result in NO_MODIFICATION_ALLOWED_ERR DOMException. Mary Brady 2001-08-17
