Document Statuses

• Working Draft: A reviewable proposal that can still change as implementations and feedback develop.
• Implementation Draft: A proposal with at least one working implementation. Details can still change before the document becomes stable.
• Stable: A specification considered suitable for broad interoperability. Changes should preserve compatibility.
• Informational: Guidance or background material that does not define an interoperability contract.
