The last bit position of the New IE Flags IE is used as the Extension Flag to allow the extension of the New IE Flags IE in the future. Extension octets of the New IE Flags IE shall follow directly after the first octet of the New IE Flags IE. When an extension octet of the New IE Flags IE is present, then all previous extension octets of the New IE Flags IE and the New IE Flags IE shall also be present, even if they have all their flag bits indicating no presence of their respective new IEs.
