Our goal (authors of draft-perez-radext-radius-fragmentation-00.txt) is to enable a mechanism for fragmentation between RADIUS packets when they exceed 4K (inter-packet fragmentation). If we remove the signal attribute (e.g. "More-Data-Pending"), the flag T should mean that the RADIUS packet is truncated (and not necessarily the attribute where the flag T is activated). For example: A,B,C,... ,Y are attributes of different types in one RADIUS packet. Adding attribute Z exceeds 4K, so we should signal that. We could decide to activate the bit T in the last attribute Y[T], but, actually, it does not mean anything in the context of extended attribute Y[T], since we want to signal that more attributes (perhaps, of any other type as, for example, Z) are coming after this list in a different RADIUS packet. In this sense, we believe that the presence of some kind of attribute "More-Data-Pending" (or any other type of signaling at packet level) can inform about this situation within the context of the RADIUS packet.
