| -- FOUNDATION DESCRIPTION: |
| -- This foundation declares a hierarchy of tagged types, which includes |
| -- both abstract and non-abstract types, and which have both abstract |
| -- and non-abstract primitive subprograms. |

| -- CHANGE HISTORY: |
| -- 06 Dec 94 SAIC ACVC 2.0 |
| -- 03 Nov 95 SAIC ACVC 2.0.1 fixes: Deleted primitive operation Proc |
| -- of Concrete_Root. |
| -- 11 Aug 96 SAIC ACVC 2.1: Changed procedure bodies to update |
| -- actual parameters. |
