6 Conformance

6.1 Introduction and topics

6.1.1 Introduction

This clause specifies the rules for producing conforming transmittal formats.

6.1.2 Topics

Table 6.1 lists the topics for this clause.

6.2 Forms of conformance

6.2.1 Introduction

An encoded transmittal may be either functionally conforming or fully conforming to this part of ISO/IEC 18023.

6.2.2 Functional conformance

An encoded transmittal functionally conforms to this part of ISO/IEC 18023 if:

1. All object instances contained therein match the functionality of the corresponding DRM classes of Part 1 of ISO/IEC 18023.
2. The object instances of the encoded transmittal satisfy the conformance requirements stated in 8.2.2 of Part 1 of ISO/IEC 18023.
3. The sequence of elements in the transmittal file set conforms to the relationships specified in this part of ISO/IEC 18023, producing the organization specified in this part of ISO/IEC 18023. For example, the transmittal root file of a transmittal file set begins with BEGIN TRANSMITTAL ROOT FILE and ends with END TRANSMITTAL ROOT FILE, and includes the information required by the productions as specified in this part of ISO/IEC 18023.
4. No elements appear in the transmittal file set other than those specified in this part of ISO/IEC 18023.

6.2.3 Full conformance

An encoded transmittal that fully conforms to this part of ISO/IEC 18023 shall:

1. be a functionally conforming encoded transmittal, and
2. conform to an encoding specified in another part of ISO/IEC 18023.

6.3 Conformance of encodings

An encoding that functionally conforms to this part of ISO/IEC 18023 shall:

1. shall only encode the abstract syntax as specified in 5.2 Abstract syntax of a transmittal, and
2. only produce functionally conforming encoded transmittals.

An encoding that fully conforms to this part of ISO/IEC 18023 shall be specified in another part of ISO/IEC 18023.
