Dan, what you are saying here is that some MARC subfields are
redundant with ISBD punctuation, which is true. This is an ongoing
argument -- why do we do both when one or the other would do that job?
That said, and in the grand tradition of inconsistency that is our
data legacy, not all fields can be parsed using their punctuation. If
you remove the subfield codes from:
650 _7 |a Silk industry |z Asia, Central |y 1860-1880.
you lose the meaning of the facets (ok, that should be in quotes) of
the topical v. date subfields. I suspect that if we looked carefully
through MARC we'd find a lot of instances of this nature.
