Publishing and unpublishing custom engines gives control to system administrators and users with manage engines permission over who can translate documents with an engine, and a way to prevent using engines in production.
The following table outlines which users can translate documents using an engine, depending on its published state:
Users with translate documents permission in the group the engine belongs to
Users with manage engines permission in the group the engine belongs to
All new engines are unpublished by default, and must be published before users with translate documents permission can use them to translate documents. This also covers usage via CAT tool plugins.
