The Fontane-TEI is far too complex to display all information in the planned
book or edition view on the website. Therefore we break it down into a simpler
format. We chose TEISimple in order to be able to re-use TEISimple's
processing models and to display the edition view in the DFG Viewer.

This is just the initial commit for the module with non-working tests -- for
some reason inspect:module-functions doesn't find any functions. Even the
examples provided on exist-db.org don't seem to work in exist-db 4.2.0.
