Rule Definition
Unreferenced Sections and Paragraph may be the symptom of Dead Code. Dead Code must be avoided as it makes source code less readable and increases the cost of the software maintenance. Warning: Unreferenced code can also be the symptoms of missing code (code not included in the source code analysis).

Remediation
Check if the Artifact is truly unnecessary. Then remove Artifacts that are not used.
