27 -- FOUNDATION DESCRIPTION:
28 -- This package declares three abstract types for use in C660 series
29 -- tests, Alert, Special_Alert, and Private_Alert.
30 -- It models (in miniature) an application situation in which an
31 -- abstraction is defined in terms of structure (record and operations
32 -- on the record) but not in terms of content (record is null). It
33 -- also models a situation in which an abstraction includes some
34 -- specific, implementation dependent, information.
