In the restructuring of the standards proposed in the following section, it becomes clear that many of the requirements are repeated across many of the sections. This is one of the biggest weaknesses of the document. Where terms are used unambiguously, and interpretation of terms made consistently, then a certain amount of redundancy can strengthen a requirements document due to a type of internal self-verification and intuitive error correction. However, in the standards document, as presented, this redundancy and repetition increases the risk of the underlying requirements model being misunderstood. See section 6.2 for an example.
