Dear Eric,
In IVD Adobe-Japan1 many codepoints with just one glyph are included,
which since adobe is the first to registar a collection makes sense to
me. However according to <http://www.unicode.org/reports/tr37/> any
collection could also do the same thing. This would mean that for one
code point that was in N collections it could have N VS that were all
identical glyphs, would it not be better to change tr37 so that
duplicate glyphs in the IVS are not permited for any one codepoint,
but rather the same VS could be named in more that one collection.
This still allows people to put what they want in a collection of
glyphs, but stops the unnecessary creation of VS but does not limit
the number of collections in any way. Since no collections have yet
been registared a change like this to tr37 be possible now, and IMHO
desirable. Though such a change makes registaring collections slightly
harder (but registaring a collection is a relatively rare event), it
makes almost everything else easier.
