Wouldn't you (and others) think that the reason that such side by side
placement is common has to do with the restrictions on vertical space on
the line? I think, rather than being a feature of the *notational
system* it's a reflection of typographical constraint. Can you (or
others) corroborate or refute this?
I would suspect that the reason this shows in phonetic systems (and
polutonic Greek and Vietnamese) is that they all have in common the use
of multiple accents.
If this is indeed primarily motivated by typographic constraint, then it
would not be useful to invent a new mechanism to encode a rendering
issue. Instead, the explanation about permissible typographic variation
in rendering stacked accents ought to be expanded/clarified, including
and explanation of when and how common such variations are employed.
