Title: Prefix Flag Extension for OSPFv2 and OSPFv3

Abstract:
Within OSPF, each prefix is advertised along with an 8-bit field of
capabilities, by using the Prefix Options (OSPFv3) and the flag
flield in the OSPFv2 Extended Prefix TLV (OSPFv2). However, for
OSPFv3, all the bits of the Prefix Options have already been
assigned, and for OSPFv2, there are not many undefined bits left in
the OSPFv2 Extended Prefix TLV.
This document solves the problem of insufficient existing flags, and
defines the variable length Prefix attributes Sub-TLVs for OSPFv2 and
OSPFv3 respectively for the extended flag fields.

Section 2 talks of Types TBD1 and TBD2
IANA Considerations asks IANA to assign TBD and TBD.
I think that these need bringing in line
