Summary

Simple Extension with the type Coding: Tham chiếu structured tới văn bản pháp luật làm căn cứ cho profile/element/invariant. Mỗi extension trỏ đến 1 concept trong VNLegalDocumentRefCS — ưu tiên hơn citation inline ở Description, vì:

• Truy xuất được issuanceDate, effectiveDate, status (in-force/future-effective/superseded) qua concept lookup
• Tooling có thể validate citation hết hiệu lực
• 1 nguồn truth duy nhất khi văn bản thay đổi Có thể dùng nhiều extension trên cùng artifact để tham chiếu chain (ví dụ NĐ 98/2021 + NĐ 07/2023 + NĐ 04/2025). Context: ElementDefinition (cho element-level) và StructureDefinition (cho artifact-level).
