| * <p> |
| * When a Composite or Object is declared in the assembly phase, and no visibility is set, only other |
| * composites/objects within the same module can use that declaration. For a declared composite/object to be usable |
| * from other modules a higher visibility must be set, either that the Composite/Object can be used by others within |
| * the same Layer, or even to be used by those in the layer above. |
