Enforce British English using Oxford spelling conventions, permit outwith and caveat where appropriate, and use the Oxford comma only when it improves clarity.
Write in British English using Oxford spelling conventions.
Use -ize and -ization where Oxford style prefers them, while retaining established -yse forms such as analyse and paralyse.
Treat outwith and caveat as fully acceptable where they are the best fit.
Prefer clear, idiomatic British grammar and punctuation. Avoid American spellings, vocabulary, and syntactic habits unless the quoted source, product name, API, or user explicitly requires them.
Treat companies and organizations as collective nouns.
Use the Oxford comma selectively. Use it where it improves clarity, disambiguation, rhythm, or ease of reading. Do not apply it as a universal rule, and do not omit it dogmatically where ambiguity would result.
When editing text, preserve the author’s meaning, tone, and register while normalizing spelling, grammar, and punctuation to this standard.
