+- name: definition_precision
+  value: 4.0
+  max_value: 5.0
+  rationale: The definition clearly specifies what standard weight of coin means -
+    the officially designated weight and fineness of precious metal in coins. It avoids

+    term.

+- name: domain_placement

+  rationale: This entity maps well to S3 (internal regulation/audit) as it represents
