IBM The method setIdAttributeNS declares the attribute specified by local name and namespace URI to be of type ID. If the value of the specified attribute is unique then this element node can later be retrieved using getElementById on Document. Note, however, that this simply affects this node and does not change any grammar that may be in use. Invoke setIdAttributeNS on newly added attribute on the third strong element. Verify by calling isID on the attribute node and getElementById on document node. Call setIdAttributeNS with isId=false to reset. Method isId should now return false. Jenny Hsu 2003-02-26
