The editing functionality is delegated to the CMS. Respectively content changes flow through the exact pipeline as changes originated directly from the CMS would. In fact, we allow the CMS to completely control the actual editing experience.

The main point of this feature is that if an employee does find a typo on some article, they can just fix it rather than going to the CMS, finding the actual place where that text is stored, making the change, etc.

It's both inline editing and the ability to link arbitrary rendered text to its originating CMS and content flow.

More detail here of how this scales to any content model complexity:
