2. Conventions

In this document, the key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" are to be interpreted as described in BCP 14, RFC 2119 [RFC2119].

Syntax definitions are written according to the <SyntaxDescription> ABNF [RFC4234] rule specified in [RFC4512], and matching rule definitions are written according to the <MatchingRuleDescription> ABNF rule specified in [RFC4512], except that the syntax and matching rule definitions provided in this document are line-wrapped for readability. When such definitions are transferred as attribute values in the LDAP protocol (e.g., as values of the ldapSyntaxes and matchingRules attributes [RFC4512], respectively), then those values would not contain line breaks.
