On the upcoming LATIN LETTER SMALL CAPITAL Q

[Yifán Wáng]

Please excuse my serial posting.

I recently noticed the subhead given to the LATIN LETTER SMALL CAPITAL
Q in the following document (at A7AF) is "Letter for representation of
morpheme in Japanese".
http://www.unicode.org/L2/L2016/16381-n4778r-pdam1-2-charts.pdf

However, to my knowledge, the letter is required for describing a
"phoneme" of Japanese that isn't tied to specific "morphemes" (~
"words"). I have contacted the original writer of the proposal:
http://www.unicode.org/L2/L2015/15241-small-cap-q.pdf
and he agrees with me in this regard.

Thus I suppose "Letter for Japanese phonology" would be more desired a
heading for this character, though subheads are not normative. What
are your thoughts?
