Yes, I can see that from the code.  It doesn't seem to do anything out
of the ordinary with this variable.

I'm glad you can understand that help documentation!  I cannot figure
out what "... load that file _outside_ any bindings ..." actually
means!

Good question.  I'll see if I can figure this out (and play with your
code) in due course.  In the meantime, I had to give up and have
prepared my tj file directly (which is not that onerous of course).
When this project bid is finished, I'll come back to this.

Thanks again for your help,
