True/False: Some normative pages contain sections labeled as 'trial use'.

• A. Unclear
• B. True
• C. False
• D. N/A

Answer: (B)

In FHIR, even when a page is considered normative, the standard often evolves by testing new ideas with implementers. To support this, the specification may include sections labeled "trial use" that describe elements or features currently in a testing phase. These sections tell you what is experimental, how to implement it for evaluation, and what feedback is being sought, while the rest of the page remains normative. Seeing a "trial use" section on a normative page indicates that part of the content is still under evaluation and may change before becoming normative. So, it’s true that some normative pages contain sections labeled as 'trial use'.
