Part Three. The Annexes - Ada 95 Rationale
The first two parts should have given the reader a good understanding of the Core of Ada 95. This third part describes the material in the Annexes. This includes the predefined environment which is mandatory, as well as the various specialized annexes themselves. It should be noted as a general principle that the annexes contain no new syntax. They are hence largely a description of various packages, attributes and pragmas.
