I don't think AACR2 falls into this category, and I think that
following the path of registering it as an encoding scheme would be
extremely unwise. Best would be the use of files like LCNAF, rather
than the mushiness of saying, oh yes, I used AACR2 rules for this,
but leave no way to validate that assertion. MARC asserts that a
record follows AACR2 rules at the record level, not the field
level--much more intelligent. Lets face it, this is yet another place
where DC IS NOT MARC--lets use each where they make the most sense
and not try to muddy the waters and drive ourselves nuts.
Temperately, as usual,
