10、served 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 partici- pate in the development of International Standards throu

11、gh 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

12、take part in the work. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technic

13、al committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent ri

14、ghts. ISO and IEC shall not be held responsible for identifying any or all such patent rights. International Standard ISO/IEC 13673 was prepared by ANSI (as ANSI X3.190) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in pa

16、eralized Markup Language (SGML), define when a sys- tem is a conforming SGML system. The determination of whether a system is a conforming SGML system is of value both to potential users of such systems and to their developers. This determination is, however, a complex process. To this end, efforts

17、are underway to develop test suites to validate conformance. Stan- dardization of development and use of test suites assures consistency of results and informs the public of the implications of the tests. Such formalism is provided by this standard, which includes guidelines for the content of indiv

18、idual tests; rigorous conventions for naming test cases and the constructs used within them; formatting and comment conventions; conventions for classifying test cases; conventions for documenting test suites; definition of a Reference Application for SGML Testing (RAST) that indicates how an SGML p

19、arser interprets a test; definition of a Reference Application for Capacity Testing (RACT) that reports a parsers capacity calculations; conventions for reporting a systems performance on a test suite. This standard also addresses conformance to the related standard, ISO 9069:1988, Information Proce

This standard may be used by those who develop SGML test suites, those who build SGML systems to be evaluate

21、d by such suites, and those who examine an SGML systems performance on a test suite as part of the process of selecting an SGML tool.

22、tion Conformance testing for Standard Generalized Markup Language (SGML) systems 1 Scope This standard addresses the construction and use of test suites for verifying conformance of SGML systems. Its provisions assist those who build test suites, those who build SGML systems to be eval- uated by suc

23、h suites, and those who examine an SGML systems performance on a test suite as part of the process of selecting an SGML tool. In particular, this standard includes: criteria for the organization of test suites, including naming conventions, documentation conventions, and specification of applicable

24、con- crete syntaxes and features. Among other advantages, these conventions facilitate any non-SGML automatic processing that may be convenient for the developers or the users of the tests; NOTE An example of such non-SGML processing is sorting tests by name. a standard form for describing test resu

25、lts that makes clear what has been proven or dis- proven by the tests; the specification of a Reference Application for SGML Testing (RAST) that interprets all markup to allow machine comparison of test results for documents conforming to ISO 8879. RAST indicates in a standard way when tags, process

26、ing instructions, and data are recognized by the parser, replacing references and process- ing markup declarations and marked sections appropriately. RAST tests information likely to be passed by a general-purpose SGML parser to an application but does not test additional informa- tion that some par

27、sers provide; the specification of a Reference Application for Capacity Testing (RACT) that reports a vali- dating parsers capacity calculations. An SGML system that supports this application indicates its ability to report capacity errors regardless of whether it supports variant capacity sets; the

28、 specification of test procedures related to SDIF data streams. This standard applies to the testing only of aspects of SGML implementation and usage for which objective conformance criteria are defined in ISO 8879. NOTE Among the aspects of an SGML system not addressed by this standard are error re

29、covery, phras- ing of error messages, application results, and documentation (including the system declaration). 2 Normative references The following normative documents contain provi- sions which, through reference in this text, constitute provisions of this International Standard.

33、S G M L support facilities SGML Document Interchange Format (SDIF) 3 Precedence of ISO 8879 Any discrepancy between any provision of this standard and ISO 8879 should be resolved in accordance with the latter. Furthermore, should any future effective edition of ISO 8879 contradict any provision of t

34、his standard, a test suite for the future version will be considered to conform to this standard only if the discrepancy is resolved in accordance with the effective edition of ISO 8879. In particular, the precedence of ISO 8879 applies to the definitions in clause 4, the description of RAST in clau

35、se 14, and the description of ESIS in annex A. Should there be any internal inconsistencies within this standard between annex A and the remainder, implementors of conforming test suites shall rely on the provisions in annex A. 4 Definitions NOTE None of the terms defined below are used or defined i

36、n ISO 8879. Should such definitions be added to some future version of ISO 8879, the prece- dence of ISO 8879 will apply in accordance with clause 3. 4.1 anomalous test case: A test case that devi- ates from some requirement of ordinary tests because the tested SGML construct is incompati- ble with

37、that requirement. 4.2 application modules: Components of an SGML system other than the parser and entity manager. 4.3 effective edition: The current edition of a standard including any amendments, addenda, or other modifications. 4.4 Element Structure Information Set: Infor- mation comprising the el

38、ement structure that is described by SGML markup (the element structure information set is defined in annex A). 4.5 ESIS: Element Structure Information Set. 4.6 equivalent SGML documents: SGML doc- uments that, when parsed with respect to identical DTDs and LPDs, have an identical ESIS. 4.7 internal

39、 entity: An entity whose replacement text appears in an entity declaration. 4.8 lexicographic order: An order in which dis- tinct strings are arranged by comparing successive letters. One string appears before another if it is a prefix of the second, or if, according to the following conventions, in

40、 the first position where they differ, the character in the first string precedes the char- acter in the second string. Printable characters precede nonprintable characters. One printable character precedes another if the ISO 646 charac- ter number of the first is smaller than the ISO 646 character

41、number of the second. In particular, the space character precedes all other printable char- acters and any other printable character precedes a second one if the first precedes the second char- acter in the list of printable characters given in 4.14. A nonprintable character precedes another if its

42、character number in the document character set is smaller than the character number of the second in the document character set. NOTE For strings consisting only of printable char- acters, this order is independent of concrete syntax. 4.9 major SOO: A statement of objective for sev- eral related tes

43、ts in a test suite. 4.10 markup-sensitive SGML application: An SGML application that can act on SGML markup as well as element structure. 4.11 minor SOO: A statement of objective that describes the particular principle of the SGML lan- guage that distinguishes an individual member of a group of rela

44、ted tests. 4.12 nonprintable character: A character that is not a printable character (see 4.14).
