          <description> The "removeAttributeNS(namespaceURI,localName)" removes an attribute by local name and namespace URI. If the removed attribute has a default value it is immediately replaced. The replacing attribute has the same namespace URI and local name, as well as the original prefix. Retrieve the attribute named "emp:local" from emp:address node, then remove the "emp:local" attribute by invoking the "removeAttributeNS(namespaceURI,localName)" method. The "emp:local" attribute has a default value defined in the DTD file, that value should immediately replace the old value. </description>
