Thanks for giving me the hand!
You can specify when there is an unambiguous behaviour to be followed.
Unfortunately, this is not always the case.
Example 1, Hindi: should the I matra precedes the whole cluster, or only the
last freestanding consonant, in the case of a cluster constituted from two
or more visually distinct components?
Example 2, Malayalam: dead RA can come either _before_ the (last part of
the) consonant, or _below_ it.
Not _quite_ the same thing, particularly if you contrast it with the fact
that Uniscribe (and several similar rendering tools) will reorder the
leading RA before the consonant in the backing store, but it will not do
this reorder for a subjoined RA...
Example 3, Malayalam again: the matra for AU U+0D4C can be shown either as
two parts (as depicted in the tables), or only as the right part.
Now what exactly can *mandate* the Standard (if it were in charge of, which
it is not, as I remember earlier)?
