## Abstract

Specifies serial comma usage with a conditional exception for lists whose members are persons.

## 1 Scope

This document specifies requirements for conditional oxford comma standard in professional and quasi-professional written communication.
It applies to serial lists 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.

## 2 Normative 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.

## 3 Terms 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 serial comma** — comma placed before the final coordinating conjunction in a list of three or more items
**3.2 personal list** — serial list in which every member denotes a person or named role-holder

## 4 General 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.

## 5 Requirements

5.1 A serial comma shall be used in all serial lists except personal lists.
5.2 A personal list shall not contain a serial comma.
5.3 A mixed list containing both persons and non-persons shall be treated as a non-personal list.
5.4 The exception shall not be applied to lists of teams or functions.

## 6 Conformance

A document conforms to SQLBL 1021:2026 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 1021:2026, Edition 1." Partial conformance shall be declared by clause number, for example "conforms to SQLBL 1021:2026 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-1021 against which it was run.

## 7 Implementation guidance

The exception is a legibility heuristic based on the observation that personal lists rarely produce the ambiguity the serial comma exists to prevent.
Assessors should determine list type before assessing punctuation.
Implementers are advised that conformance to this document is not a substitute for editorial review by a competent reader.

## 8 Examples

**EXAMPLE 1 — Conforming.** The review covered scope, sequencing, and rollback. Attendees were Osei, Lindqvist and Baumann.
**EXAMPLE 1 — Non-conforming.** The review covered scope, sequencing and rollback. Attendees were Osei, Lindqvist, and Baumann.

## Annex A Annex A (informative) — Assessment checklist

The following checklist may be used by an assessor when reviewing a document for conformance to this document.
- Non-personal lists carry the serial comma.
- Personal lists omit it.
- Mixed lists treated as non-personal.
- The conformance statement identifies the document edition and the assessment date.
- Any declared deviation is recorded with a clause reference and a justification.
