Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).

Introduction
This document specifies the conformance and reference software for the ISO/IEC 23005 series. The
conformance and reference software serves three main purposes:
— validation of the written specification of the several parts of ISO/IEC 23005;
— clarification of the written specification of the several parts of ISO/IEC 23005;
— conformance testing for checking interoperability for the various applications against the reference
software which aims to be compliant with ISO/IEC 23005.

5 Conformance for the ISO/IEC 23005 series
5.1 General
This subclause defines conformance for the ISO/IEC 23005 series. A bit-stream is compliant to the
ISO/IEC 23005 series if it conforms to the conformance definitions specified in 5.2 and 5.3.

5.2.1 Overview
This subclause defines a validation schema based on ISO/IEC 19757-3 to check the conformance bit-
streams (XML descriptions) that conform or do not conform to the normative clauses of the other parts
of ISO/IEC 23005 and descriptions thereof. In particular, the additional validation rules as specified in
the other parts of ISO/IEC 23005 are checked with this validation schema. The actual schema can be
found in 5.2.2 and a more readable version of the rules and assertion messages is provided in 5.2.3. The
actual conformance bit-streams (XML descriptions) are defined in 5.2.4. The actual conformance bit-
streams and corresponding code can be found attached to this document.
For transforming the validation schema according to ISO/IEC 19757-3 and for validating the examples,
[6]
Saxon is used. Saxon is not mandatory and other tools can be used for validating the examples.
