This allows administrators to define a regular expression to filter content
entered into short answer fields by agents and endusers. With the new
visibility feature, the regular expression input is only shown if the
regular expression validator is selected.

should be hidden based on values of other fields in the same form.

Validation is not performed on fields server-side if they are considered
invisible when submitted.
