XML used to be the default choice for e-learning as far as I understand.

There are effectively two parts of the framework where JSON is loaded and can be swtiched to XML or similar. src/core/data.js - where the data is loaded into the course at runtime, and the grunt/ folder - where data is checked for structure and used in the build process.

You're more than welcome to make a pr to allow Adapt to switch between JSON and XML. Deciding on how to structure the xml might be somewhat of a challenge. Persoally I find the extra characters a bit mind blowing.
