Selwyn,
Generally I think you should write a usage message for each option name and
value that is unique to your package.
Sometimes you may overload a name already used in Mathematica. You can then
add to the usage message for that name. For example the following is used in
my Algebra`PushThrough` package
$NewMessage[Constants, "usage"];
Constants::usage =
Constants::usage <>
" For the PushThrough routine, Constants specifies a list of symbols \
which will be treated as constants and not pushed through.";

A programming question:
In general, what context should be given to symbols representing option
names?
For instance, let's say I'm writing a package with context Foo`foo`,
and a function in the package has an option named ColorSpec. In what
context should ColorSpec exist? Or does it really matter?
