Xara sorted things out. Elements is simply a rename of the Online Content Catalogue (OCC)

Look at https://www.xara.com/elements/ for a sensible description.
Do note, Elements is not part of the Perpetual purchase, only the Plus Products.
Most legacy (Xara's wording) Magix desktop applications will have lost or soon will lose access to the OCC as the Magix Update Service no longer exists. v10/v11 OCC is still available as it was before Magix and the paywall of templates, widgets and content that we now endure.
If you are still active, remember to use Download All in the Local Designs gallery folders to get an off-line set of templates and widgets. Don't lose what you've paid for.
