Yes: I've never felt that was one of the most elegant properties of the

I think you have to do 1. A common scenario is to have A and B as
alternative entry points with the bulk of the real logic in C: so the user
can invoke A or B as the entry module, and both of these import C.

Even if 2 yields one stylesheet A that imports all the others (say B, C, and
D), that doesn't stop B being a valid entry point.

To take a concrete example, when I format the XSLT spec for publication, B
is the entry point for producing the main published document; A (which
imports B) is an overlay that produces the version with diff markup.
