since : and - are not lowercase characters, just "any lowercase letter"
would work... or by AND do you mean "followed by"?

[a-z] is a lower case letter (in ASCII...)
[a-z \- - \:] allows any character in two ranges:
(1) a .. z
(2) - .. :
using the default collation/sorting sequence, this gives (consulting an
ASCII or Unicode chart)
- . / 0123456789 :

This therefore matches pastry:36-little-pigs but not flat:pan_cake

It might be, but there are no nested square brackets in your example.
The stylesheet you appended had the range --- in it, rather than --: by
the way.

Note that we are using here XPath 2 regular expressions, not Java ones.
They are very close (and both are more or less subsets of Perl regular
expressions, which are much more powerful).
