Principles for Documentation of Statements

In the following sections of this document, the different statements are described. These descriptions have a common layout:

• The purpose of the statement is described.

• The formal and strict syntax of the statement is defined using the meta language.

• Comments are made on the interpretation of the syntax.

• Examples are given.

Remark:

The formal syntax has sometimes consciously been made somewhat imprecise to avoid making it too heavy. For instance, the delimiter is normally supposed to be repeated in repetitions even if not explicitly denoted.

A general rule is: Terms are always separated by one delimiter
