Logical Structure of the Specification
- The source files are grouped in planes and components - according to the following table. - A notation file covering the whole specification is provided. - The notation for the relations or functions introduced in each file - is shown in parentheses (? are placeholders). + Logical Structure of the Specification + This table reports the specification's components and their planes.
