          <description> The method insertBefore inserts the node newChild before the existing child node refChild. If refChild is null, insert newChild at the end of the list of children. A NO_MODIFICATION_ALLOWED_ERR is raised if the node is read-only. Using insertBefore on this Document node attempt to insert a new Attr node before this DocumentType node and verfiy if a NO_MODIFICATION_ALLOWED_ERR is raised. (This can also raise a HIERARCHY_REQUEST_ERR and NOT_FOUND_ERR) </description>
