Ah, see, I knew that was the intent all along.  This is another attempt
to force IDN to perform 1-to-1 TC/SC mapping by having IETF "publish"
the proposed table in the stringprep document and then insisting that
IDN implement the conversions specified in the "official" table.

TC/SC equivalence is not 1-to-1.  Implementations that pretend that it
is will confuse and mislead Chinese speakers who expect true,
context-based equivalence.  Domain operators who implement 1-to-1 TC/SC
mapping tables are out of conformance with the IDN proposal.
