Modification timestamp for documents in a BaseX database

Question

I have a gnu make system, and would like to trigger rules based on updates to documents in a BaseX XML database. In other words, something like archive(member) can be used in gnu make to refer to a member of an archive, I would like to use db(foo.xml). Or, since that's probably not possible, some workaround involving creating dummy files with the correct timestamps, but I can't even figure out how to retrieve the modification date from a document in a BaseX database.

Answer 1

Marking as an answer that BaseX does not maintain document modification times.
