Section 27 of 105
26. Rule Title and Rule Statement
Stable section ID: S05-CON-014-SECTION-27 · 18 content blocks
Each Rule shall contain one concise title and one independently understandable normative statement.
The title shall identify the required outcome or controlled subject. It shall not carry the full legal or engineering obligation.
The Rule statement shall:
- Use defined normative language.
- Identify the responsible subject where necessary.
- State the required or prohibited outcome.
- Define essential applicability conditions.
- Avoid combining unrelated obligations.
- Avoid vague adjectives without measurable meaning.
- Avoid depending on rationale or examples for interpretation.
- Remain understandable when retrieved outside its source chapter.
A preferred structure is:
When <applicability condition> exists, <responsible subject> SHALL <required outcome> within <defined limit or condition>.
A prohibition may use:
<Responsible subject> SHALL NOT <prohibited action> when <condition> applies.
Compound Rules should be divided when their obligations require different applicability, verification, evidence, authority, or lifecycle states.
The title and statement shall use controlled System05 terminology. Synonyms shall not be introduced where a defined term already exists.
Informative explanations shall remain outside the normative statement.
