* Hack: Fix a parsing error in the DM XML in a way that can be side loaded for SVE

Note: We do have a proper fix for this, but it requires re-rolling
the test harness. This is a backup in case we don't have time to
do this.

* Restyled by isort

* add issue number, remove print

* Add the remaining data model file patches

* add other DM patches

* Restyled by autopep8

* omg...add the changes, cecille

* whoops
