But if you're writing the stylesheet that's being imported/included,
then you don't know what it's (going to be) imported/included into.  I
think that's what Dylan's talking about.

Dylan, I'd declare the variable in the stylesheet you're writing, but
with a nonsensical or otherwise unique value, and then test the value
of the variable - if it's that value, then you know the
importing/including stylesheet hasn't overridden (declared) it.

I hope that helps,

Jeni
