It is based onthe normative content of ISO/IEC 13522-5:1997, in constituting a new notation of MHEG-5 classes.ISO/IEC 13522 consists of the following parts, under the general title Information technology Coding ofmultimedia and hypermedia inf

Annexes B and C are for information only.ISO/IEC 13522-8:2001(E) ISO/IEC 2001 All rights reservedvIntroductionThis part of ISO/IEC 13522 specifies

40、a third formalnotation based on XML for ISO/IEC 13522-5:1997.At present the normative components of ISO/IEC 13522-5:1997 are unambiguously expressed in ASN.1 and EBNFtextualNotation. Both of these formats are wellknown to most software specialists. But it is thought that thestandard would attract a

41、wider user community if a more familiar markup language was used to express theelements of the Standard. XML has been suggested as the appropriate markup language to use because a verylarge number of WWW authors already use HTML; and both XML and HTML have a common ancestor in SGML.Many applications

42、 or application components may be retrieved from the Internet or written by persons who know oruse HTML document formats; thus an MHEG-5 engine capable of processing objects expressed in XML wouldappealto a wide audience of potentialusers. Materialstored on Intranet servers in XML format might also

43、be easilyand quickly inserted into broadcast applications. In addition it is expected that the WWW and MHEG technologieswill eventually merge. Hence an XML version of MHEG-5 may be consistent with this process when it begins totake place.In XML, a DTD (Document Type Definition) defines a verifiable

44、syntax for a class of XML documents. This part ofISO/IEC 13522 expresses a DTD defining a notation for encoding MHEG-5 objects; this DTD is given in Annex A.ISO/IEC 13522-8:2001(E) ISO/IEC 2001 All rights reservedINTERNATIONAL STANDARD ISO/IEC 13522-8:2001(E)1Information technology Coding of multime

45、dia and hypermediainformationPart8:1 ScopeISO/IEC 13522-5:1997 specifies two functionally equivalent notations for MHEG-5 objects in Annexes A and B ofthat document. This part of ISO/IEC 13522 specifies a third functionally equivalent notation for MHEG-5 objects inXML 1.0 (“Extensible Markup Languag

46、e“ as recommended by World Wide Web Consortium, W3C). Thisspecification is unambiguously expressed in the DTD contained in Annex A.This part of ISO/IEC 13522 in no way invalidates or substitutes for any clauses of ISO/IEC 13522-5:1997.2 ConformanceThispartofISO/IEC13522definesanalternativenotationto
