Just to verify that all suffixes connected by the NNBSP start with a Mongolian letter.
All that I know of are listed in the document sent out earlier - DS05.

I'm assuming that MSuffix always starts with a letter.  There seems to be no need to make Mongolian letters a special type of letter - ALetter suffices.

MidLetter doesn't work with (c), nor does MidNumLet.  The UTC is offering ExtendNumLet, which will cover all but (e).

Nothing covers (e).  For example, English "word(s)" is split so that the words are "word" and "s".

Although it is covered, is (f) suitable for the start of a line?
I'm not sure that the NNBSP can be rendered properly in such cases.
Would "ZWJ MSuffix" suffice where "MSuffix" was insufficient?

Should NNBSP ever be at the end of a line?  If it is given a general category of Pc rather than Zs, it is likely to be displayed.  Perhaps this does not matter.

Richard.
