Brian,
This could be taken two ways: either (portions of) the RFC must be
assumed to be meaningless except in the context of prior discussions on
the E-Mail list (hence, only somebody who has read the entirety of the
IPv6 mailing list is qualified to read and ask questions about this RFC),
or those same parts of the RFC do not provide sufficient clarification
of intent.
Surely you're not saying everybody should familiarize themselves
with all of the discussions from the mailing list in order to understand
the RFC.
The prior discussion does not actually address the question - except
that it might have provided enough clue to make someone stop asking at the
time.
In both discussions, disparity between definition and format means
that a very large number of addresses are somehow reserved (apparently for
future use). Any address that starts with '1111111010b' is a link-local
address (with the last 64 bits are used to provide an interface identifier)
according to the definition - except that all values in the fe80::/10 range
that do not start with
'1111111010000000000000000000000000000000000000000000000000000000b'
are (currently?) invalid.
IMO, while the meaning may be fairly clear given the discussions
that have occurred, the fact that this was discussed before and is being
discussed again is a pretty good indication that it will be discussed at
least one more time unless it is documented somewhere other than in E-Mail.
Is it possible to provide clarification in the form of an errata?
