Nicholas Shanks:
I hope the following aids matters.
Aids? :)
Situations where expansions of abbreviations are needed:
1) People unfamiliar with the topic being discussed.
This includes adhoc abbreviations, which I frequently use in table
headers.
2) Documents that exist as both a single page, and as multiple pages
3) Documents that use the same acronym to mean different things in
different contexts/sections.
4) Documents where the acronym and an identically spelled word appear.
I forgot so far to mention my dearest English abbreviation, actually
it is a (NIST-recommended) unit symbol and thus without the abbrev
dot: 'in' for inch. Unit symbols and abbreviated function names (e.g.
'sin') also may need markup (and styling) to keep them upright inside
italic mathematic text (not every italic math is a |var|).
FWIW, I agree with Nicholas on everything else in his e-mail.
