1.4 Conformance Requirements
To conform to [ECMA-262-1999] , a user agent must provide and support all the types, values, objects, properties, functions, and program syntax and semantics described in the specification (See [ECMA-262-1999] section 2, Conformance). Any optional portions that have been implemented must also be implemented as described by the specification. Normative language is usually used to define both required and optional portions. (For more information, see [RFC2119].)
The following table lists the sections of [ECMA-262-1999] and whether they are considered normative or informative.
