   User-defined content for extensions. You can use this as you like.

   Let's say that you have an extension with the key "myext", then it is ok to define properties for:

   .. code-block:: php

      ['ctrl']['EXT']['myext'] = ... (whatever you define)

   Note this is just a convention. You can use some other syntax but
   with the risk that it conflicts with some other extension or future
   changes in the TYPO3 Core.
