Clause reference

Nobody complies with a standard in general; they comply with its clauses in particular. The clause is where the requirement lives, and clause references are the working currency of technical review — comments cite them, compliance matrices index by them, contracts incorporate by them, and expert conclusions stand on them. A finding that names its clause can be checked in a minute; a finding that gestures at a document invites a correspondence cycle instead.

The fragility of the currency is that clause numbering belongs to an edition. Standards are restructured when revised, and clause 6.3.2 of one edition may be renumbered, merged or deleted in the next — so a clause reference without a dated edition is a pointer into an unspecified document, and automated cross-references break silently when the underlying edition moves.

The craft, small but real: cite document, edition and clause together; quote the operative words where the stakes justify it; and when checking someone else's reference, verify the clause says what the citation claims — a nontrivial fraction do not, having been carried forward from an edition where they did.
