Ok, I'll take all the credit for it then... :)

That's not a better way for me.

The OP said:

"I have a stylesheet with a pipeline in it
and a large set of imported stylesheets...

I would like to deliver one expanded stylesheet."

So the requirement is to be able to combine multiple stylesheets into
a single deliverable...which "compiled stylesheet modules" would fit

The only difference I can see is that the module might not be human
readable - which is a bonus in some cases... (but you never know it
may be possible to uncompile the module).

Dimitre was after this sort of ability for FXSL a while back...  I was
after it too for a project where 2500+ lines of XSLT could've been
compiled, except that they were imported by a stylesheet comtaining a
couple of templates that was generated on the fly per transform.
Prior to that particular requirement I used a compiled stylesheet, but
afterwards I had to create a new Transformer everytime...

I really think distributing a file with paths to all the stylesheets
is a poor second to distributing a single binary.

As a middle road perhaps we could borrow from java and create .xar
files (um.. "zarr"?) with manifests that indicate the primary
