7、U-T Z.103, ITU-T Z.104, ITU-T Z.105, ITU-T Z.106 and ITU-T Z.107, this Recommendation is part of a reference manual for the language. The language defined in this document covers features of the language not included in Basic SDL-2010 in Recommendation ITU-T Z.101. These features provide comprehensi

8、ve coverage of abstract grammar of the language except some data features covered in ITU-T Z.104 (and ITU-T Z.107 for object-oriented data). Coverage The Specification and Description Language has concepts for behaviour, data description and (particularly for larger systems) structuring. The basis o

9、f behaviour description is extended finite state machines communicating by messages. Data description is based on data types for values and objects. The basis for structuring is hierarchical decomposition and type hierarchies. A distinctive feature of the Specification and Description Language is th

10、e graphical representation. This Recommendation covers additional features to Recommendation ITU-T Z.101. The concrete grammar given is the graphical representation. The alternative textual programming representation is given in Recommendation ITU-T Z.106. The concrete grammar in this Recommendation

11、 with Recommendations ITU-T Z.101 and ITU-T Z.104 (and ITU-T Z.107 for object-oriented data) gives a canonical syntax, which is extended in ITU-T Z.103 to a syntax that is easier to use. The features of the language defined in Recommendation ITU-T Z.102 make the language more comprehensive. Applicat

12、ions The Specification and Description Language is applicable within standard bodies and industry. The main application areas for which the Specification and Description Language has been designed are stated in ITU-T Z.100, but the language is generally suitable for describing reactive systems. The

13、range of applications is from requirement description to implementation. The features of the language defined in Recommendation ITU-T Z.102 allow more complex models to be defined than is practical with ITU-T Z.101, but without the features of Recommendation ITU-T Z.103 that make the language more c

14、oncise and informative. This Recommendation provides a basis for the features defined in Recommendation ITU-T Z.103, which (with ITU-T Z.104 for data and ITU-T Z.107 for object-oriented data) completes the main language feature set.

The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff quest

18、ions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations

19、 on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, t

20、he expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or a

21、pplicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance wi

22、th the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or appli

23、cability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to imple

32、nsive SDL-2010 1 Scope and objective This Recommendation defines features of the Specification and Description Language that extend the features of the Basic Specification and Description Language defined in ITU-T Z.101 to comprehensively cover the abstract grammar of the language. A canonical concr

33、ete syntax is given to cover the abstract grammar. The abstract grammar defined in this document with the abstract grammar of the Basic Specification and Description Language comprehensively defines properties of the language except the details of data and expressions. This Recommendation also inclu

34、des features for inheritance of types, generic systems, macros and the handling of the Universal Multiple-Octet Coded Character Set. Together with ITU-T Z.100, ITU-T Z.101, ITU-T Z.103, ITU-T Z.104, ITU-T Z.105, ITU-T Z.106 and ITU-T Z.107, this Recommendation forms a reference manual for the langua

35、ge. 1.1 Objective The objective of this Recommendation is to define features of the Specification and Description Language additional to those features defined for Basic SDL-2010 so that the abstract grammar of all SDL-2010 except data and expressions is defined. As well as completing the abstract g

36、rammar, the features for the inheritance of types is added. The defined concrete syntax is a canonical form that closely matches the abstract grammar. While this makes it possible to use each of the features, a separate Recommendation on shorthand notation provides additional concrete grammar that m

37、akes SDL-2010 more practical to use. 1.2 Application This Recommendation is part of the reference manual for the Specification and Description Language. The part of the language defined by this Recommendation does not usually include shorthand notation or Model sections, so that a model written usin

38、g only Comprehensive SDL-2010 or Basic SDL-2010 is not as concise or as readable as one using the full language. Shorthand notation or Model sections in Comprehensive SDL-2010 are transformed into the canonical concrete syntax given for Comprehensive SDL-2010 or Basic SDL-2010 or the data and action

39、 language in SDL-2010. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.
