• Sometimes “principle” and “principle description” are not distinguished. Thus the term “principle” may also refer to this concept.

A principle description is a document that describes a principle by giving at least the following information:

• a name for the principle,
• a description of the rule,
• and a rationale that describes why the rule holds.

Typically a principle description also gives further information like hints on when and how to apply the principle, examples, etc.

When several principle descriptions are described uniformly, this is called a principle catalog.
