Thanks for your ideas. I had considered pandoc-crossref also but didn't
want to introduce a new dependency without a real need. If it can be
accomplished using a simple and small Lua filter, I would prefer this.
I also observed that the native output creates a normal string. However,
using Pandoc's make_section function, the references are delivered as DIVs
with a number attribute. This is easy
