I've made both an entity for an en-dash and a variable for a colour in
the last two days, but I think variables are more useful since one
declaration can suffice for a modular set of stylesheets.

A variable can be visible in other files that include/import or are
included/imported by the file (i.e., the entity, in another sense of the
term) that contains the top-level variable declaration, whereas the
entity is for one file (unless you get into using external parsed
entities instead of include/import).

Tony.
