An application for a mark which does not contain the documents provided for under (a), (b), (c), (d) and (e) above shall not be entertained at the actual time of filing. The conditions to be met and the documents to be attached to the documents provided for under (a), (b), (c), (d) and (e) above shall be fixed by regulation.
