TYPO3 Core

Via TSconfig TCEFORM it's possible to set label and (since v11) also description of TCA fields.

However it was never possible to set empty labels, because the form data providers evaluating the TSconfig check for empty(), not just for isset().

For example:
TCEFORM.pages.title.label =
will be interpreted like as it was not there at all.

As an intgerator or developer, when writing such a line explicitly int my code, I'd expect that it is evaluated by the Core API.

For example I may want to unset a description in a specific page tree.

This should be generally possible for all "label-like" TSconfig settings (label and description where just an example).
