+=head2 VALIDITY
+
+Suppose the following scenario:
+
+You have a lot of parts in your database, and a set of properties cofigured. Now not every part has every of these properties, some combinations will just make no sense. In order to clean up your inputs a bit, you want to mark certain combinations as invalid, blocking them from modification and possibly display.
+
+Validity is assumed. If you modify validity, you actually save B<invalidity>.
+Invalidity is saved as a function of config_id, and the trans_id
+
+In the naive way, disable an attribute for a specific id (simple)
