I'm happy to have been helpful.

I haven't thought at lexvo. Thank you. In fact, after reading your original
question a second time, I realized that probably I misunderstood your
needs: it seems to me that in your use case you know beforehand which
language tags are involved, so that you can probably hard code the relevant
codes in the query.
