[TYPO3-english] TCA: Require one field OR the other

[Christian Weiske]

Hi,


I have a TCA record that has two fields A and B, and one of them has to
be filled.
If A is filled, B does not have to be filled.
If B is filled, A does not have to be filled.

Is this enforcable using TYPO3 standard mechanisms? How?

If not, what could I do?
