This is part of the danger of relying on online versions and not
referring to the printed version of the standards. ;-) You need to
understand the function of the online namelist -- it is used to drive
a formatting program that produces *both* the Unicode Standard's name
list and the ISO/IEC 10646-1:2000 name list. For generating the
Unicode Standard *printed* version of the name list, the parenthetical
annotations after the names are omitted. For generating the 10646
name list, all lines except the code/name/annotation line are omitted.

It *is* a note, but it occurs in the ISO Comment field in the database.
That field is there precisely to track these notes for 10646, which
are required in order to print 10646 accurately. They are not for
any other purpose, and certainly not for the general annotations that
the Unicode editors add to the Unicode Standard's name list.

Actually, it could easily be removed, but only with the concurrence
of WG2 and the ISO/IEC 10646 editor.

This clarification can easily be added to the Unicode name list.
Thank you for the suggestion.
