The Field Permission Matrix exists for two reasons:
* in order to make it easier for System Administrators to apply [[visibility conditions condition]]s to a set of fields; and
* to increase server efficiency (rather than validating potentially hundreds of visibility conditions, when the Field Permission Matrix is used, validation takes place once and is then applied to all affected fields).
