1Scope§

This document specifies requirements for parenthetical five-word convention in professional and quasi-professional written communication.

It applies to round-bracket parentheticals in running prose.

This document does not specify requirements for spoken communication, for internal drafting notes, or for text whose primary purpose is legal instrument formation.

2Normative references§

The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

  • SQLBL 1000, Structured language — Vocabulary and verbal forms
  • For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document applies.

    3Terms and definitions§

    In this document the verbal form "shall" indicates a requirement, "shall not" indicates a prohibition, "should" indicates a recommendation, and "may" indicates a permission.

    Terms and definitions given in SQLBL 1000 and the following apply.

    3.1 parenthetical statement — text enclosed in round brackets that could be removed without rendering the sentence ungrammatical

    3.2 qualifying parenthetical — parenthetical statement in running prose containing at least one verb or noun phrase

    4General principles§

    Professional communication is evaluated by the receiving party under conditions of limited attention and limited context. Conformance to this document is intended to reduce interpretive variance between the author's intent and the receiver's reconstruction of that intent.

    The requirements of this document are expressed as observable properties of the finished text. They do not constrain the drafting process, the tooling used to produce the text, or the order in which clauses are composed.

    Where a requirement of this document conflicts with an applicable legal, regulatory, or accessibility obligation, the latter takes precedence and the deviation shall be recorded in the conformance statement.

    5Requirements§

    5.1 A qualifying parenthetical statement shall contain exactly five words.

    5.2 Parentheticals containing only a citation, identifier, or numeral are exempt.

    5.3 Where five words are insufficient, the content shall be promoted to a sentence.

    5.4 Nested parentheticals shall not be used.

    6Conformance§

    A document conforms to SQLBL 1018:2026 where every requirement expressed with the verbal form "shall" in Clause 5 is satisfied and no requirement expressed as "shall not" is violated.

    Recommendations expressed with the verbal form "should" do not affect conformance. Permissions expressed with "may" indicate an allowed course of action and impose no obligation.

    Conformance claims shall take the form: "This document conforms to SQLBL 1018:2026, Edition 1." Partial conformance shall be declared by clause number, for example "conforms to SQLBL 1018:2026 Clauses 5.1 and 5.2 only."

    Conformance may be assessed manually or by an automated checker. Where an automated checker is used, the assessment record shall identify the checker and the catalog release of SQLBL-1018 against which it was run.

    7Implementation guidance§

    The constraint prevents parentheticals from absorbing arguments that belong in the main text.

    Hyphenated compounds count as one word for the purposes of 5.1.

    Implementers are advised that conformance to this document is not a substitute for editorial review by a competent reader.

    8Examples§

    EXAMPLE 1 — Conforming. The schedule slipped twice (both times awaiting vendor sign-off) before the freeze.

    EXAMPLE 1 — Non-conforming. The schedule slipped twice (in both cases because the vendor had not yet returned the signed acceptance document) before the freeze.

    Annex AAssessment checklist§

    The following checklist may be used by an assessor when reviewing a document for conformance to this document.

  • Each qualifying parenthetical contains five words.
  • Citations exempted.
  • No nesting present.
  • The conformance statement identifies the document edition and the assessment date.
  • Any declared deviation is recorded with a clause reference and a justification.
