The Authoritative Dictionary ofIEEE Standards Terms B14should be referenced for terms not defined in this Clause.3.1.1 content object: A collection of digital content that is intended for presentation to

26、 a learner by a learn-ing technology system. A content object may include learning material and processing code. Example: Acontent object might be an interactive HTML page with an embedded video clip and an ECMAScript.3.1.2 content object communication data Extensible Markup Language instance (COCD

27、XMLinstance): A particular XML representation of the data model defined in IEEE Std 1484.11.1-2004 thatadheres to the requirements and constraints of an XML binding of the data model.3.1.3 Extensible Markup Language binding (XML binding): The method of encoding the behaviors,attributes, and value sp

29、ema definition4. ConformanceThis Standard defines conforming IEEE Std 1481.11.1-2004 content object communication data (COCD)instances in an XML binding. Hereafter, such instances are referred to as “COCD XML instances.”In this Standard, “shall” is to be interpreted as a requirement on an implementa

30、tion; “shall not” is to beinterpreted as a prohibition.A conforming COCD XML instance Shall conform to the data-model requirements of IEEE Std 1484.11.1-2004. Shall not contain any extensions to the data model defined in IEEE Std 1484.11.1-2004. Shall be valid according to the XML Schema definition

Shall not contain any elements or attributes not defined in the XSD specified in Annex B. 3W3C publications are available from the World Wide Web Consortium, 32 Vassar Street, Room 32-G515, Cambridge, MA 02139, USA (http:/www.w3.org/).4The numbers in brackets correspond t

All rights reserved. 3 Shall consist of a single element and its descendants. The single element shall have the name “cocd”as defined in the XSD specified in Annex B. The

33、 single element shall reside within the scope of anamespace declaration using the namespace specified in Clause 5.NOTE 1This Standard does not require that the COCD XML instance be an XML document. The instance may beembedded at any depth in an XML data instance that includes elements from other nam

34、e-spaces.5NOTE 2IEEE Std 1484.11.1-2004 defines smallest permitted maximum (SPM) values. If a COCD XML instancecontains more than the SPM number of occurrences of a COCD element, implementers should be aware that it is notguaranteed that an application will process more than the SPM number of occurr

35、ences of the COCD element. If a COCDXML instance contains more than the SPM number of characters in a character string, implementers should be awarethat it is not guaranteed that an application will process more than the SPM number of characters in the character string.
