Perhaps a clearer distinction is needed between what compiler folks call
syntactic and semantic errors: in particular, referring to
functions/variables/templates/types that don't exist (yet) is classified as
a semantic error. Since in XSLT all of these can be forwards references
anyway, it's not just references to things declared in other modules that
are relevant, but forwards references to things in the same module.

A bit of subtle colouring for the dangling references could alert the user
to their existence without implying that the thing won't run.
