| -- TEST OBJECTIVE: |
| -- Check that an extended type can be derived in a private child package |
| -- from an abstract type defined in a library package. |
| -- |
| -- TEST DESCRIPTION: |
| -- Add a private child package to Alert_Foundation. Using Private_Alert |
| -- as parent type, declare an extended type adding a new record component. |
| -- Override procedure Handle. Declare an object of the new type in the |
| -- child specification. Use type definitions from the private part of the |
| -- parent in the body of the child. |
| -- |
| -- TEST FILES: |
| -- This test depends on the following foundation code: |
