NOTE—The term capability is used to describe a set of related detailed provisions of this standard. Each capability can comprise both mandatory provisions, required if implementation of the capability is to be claimed, and optional provisions. Each detailed provision is specified in one or more of the other clauses of this standard. The Protocol Implementation Conformance Statement (PICS), described in 5.3, provides a useful checklist of these provisions.

注意：能力这个词用来描述本标准的相关细节规定。每个能力都包含强制部分和可选部分。每个能力的详细规定参见本规范其余章节。5.3说明了协议实现的一致性声明，提供了很有用的检查清单。

5.3         Protocol Implementation Conformance Statement

The supplier of an implementation that is claimed to conform to this standard shall complete a copy of the PICS proforma provided in Annex A and shall provide the information necessary to identify both the supplier and the implementation.

参见附件A。
