From eb3b4d9b3fa3892c838a6182632019ec8ac142ae Mon Sep 17 00:00:00 2001
From: Carl Wilson <carl@openpreservation.org>
Date: Wed, 8 Nov 2023 14:35:33 +0000
Subject: [PATCH] FIX: Issue parsing not well formed manifest XML

- added null manifest tests to `PackageParserImpl`;
- same for `ValidatingParserImpl`;
- added test file and unit test for diagnosis and regression protection;
- bumped Maven version to `0.9.1`; and
- updated docs with the new version.
