Islandora Paged Content contains a dependency on the XACML Editor which is not in the module .info file nor in the documentation, which can be seen here:
In some cases (when using the zip importer for example) the ingest process will fail if XACML editor is not present.
This dependency should either be documented or removed. Some discussion of how to remove it has taken place on this now-closed Pull Request. https://github.com/Islandora/islandora_paged_content/pull/60
