2. Notational Conventions

Cette page resume la section correspondante du RFC 9982 et conserve les points essentiels sur JSContact, vCard et les registres IANA.

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" are interpreted as described in BCP 14 [RFC2119] [RFC8174] when they appear in all capitals.

ABNF definitions use the notation of [RFC5234]. ABNF rules not defined here are defined in [RFC5234], for example CRLF, WSP, DQUOTE, VCHAR, ALPHA, and DIGIT, or in [RFC6350].
