Yes, it does.

OK, I had a look at org-export-backend, but not sure what I'm looking
for in particular.  

I did note that you don't test back-end directly, but instead look at
org-export-backend-name. Perhaps this is what Nicolas means by "Filters
defined here shouldn't make a back-end test, as it may prevent back-ends
derived from this one to behave properly"?

However, changing my filter so it uses org-export-backend-name doesn't
seem to change anything.

Or, was I supposed to learn something else from ox.el?

Thanks for your help.

All the best,
Tom
