work on docx files directly

[dariok]

Saxon has EXpath and thus expath-zip or expath-archive, respectively.

These can be used to work on docx directly.

Create Flat OPC from this and adapt other scripts to work on that hierarchy

Can you pls provide minimal documentation on how to use commit 5e8927a?
Tried from within oXygen and from saxon-HE cli, both to no avail… Most likely I missed something obvious, like getting EXPath to run properly…
