Certainly: but the "mandatory" concept is missing in the standard (or I
don't
know where it is). I accept the fact that an information may be necessary
for the interpretation of the standard, and in proposals. Now we can
agree...
as long as the necessary informations are also published.
If there are information in proposals that are not included in the standard,
all interpretations become possible. The glyph as well as added ISO
comments in the UCD, are good. But I wonder if all comments like informative
names or linguistic usage found in charts are also found in a data file
(except
for Han characters which have extensive information in UniHan.txt, even if
this
information is still incomplete or may still contain errors).
So when the glyph is wrong in the standard, it must be corrected to remove
the possibility of false interpretations, which may produce
incompatibilities
notably when creating charset mappings, transliteration algorithms, or
custom
foldings.
