Add Connectors To Locked Elements

Generally, when working in a diagram containing locked elements, you cannot add a connector to a locked element. However, this depends on the lock status of the source and target elements (or more precisely, the lock status of the parent packages of the source and target elements, when the source and target element are held in different packages). There are scenarios in which a connector can be created on a locked element.

The exception is Composition connectors, where the target (the parent) must be unlocked - you are modifying the parent by adding children
