1.1 Terminology

addBIn this specification, where they appear in upper case, the words "MUST", "MUST NOT", "SHOULD", "SHOULD NOT", "MAY", "REQUIRED", and "RECOMMENDED" are to be interpreted as described in [RFC2119].

addGAs is indicated in [conformance], conformance criteria for serialization are determined by other specifications that refer to this specification. A serializer is software that implements some or all of the requirements of this specification in accordance with such conformance criteria. A serializer is not REQUIRED to directly provide a programming interface that permits a user to set serialization parameters or to provide an input sequence for serialization.

addG Implementation-defined indicates an aspect that MAY differ between serializers, but whose actual behaviour MUST be specified either by another specification that sets conformance criteria for serialization (see [conformance]) or in documentation that accompanies the serializer.

addG Implementation-dependent indicates an aspect that MAY differ between serializers, and whose actual behaviour is not REQUIRED to be specified either by another specification that sets conformance criteria for serialization (see [conformance]) or in documentation that accompanies the serializer.

addG In some instances, the sequence that is input to serialization cannot be successfully converted into a sequence of octets given the set of serialization parameter ([serparam]) values specified. A serialization error is said to occur in such an instance. In some cases, a serializer is REQUIRED to signal such an error. What it means to signal a serialization error is determined by the relevant conformance criteria ([conformance]) to which the serializer conforms. In other cases, there is an implementation-defined choice between signalling a serialization error and performing a recovery action. Such a recovery action will allow a serializer to produce a sequence of octets that might not fully reflect the usual requirements of the parameter settings that are in effect.
