The work of preparing International Standards is normally carried out through
11、 ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborate
12、s closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. 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 cri
13、teria needed for the different types of ISO documents 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).

18、5-2. This schema can be used to validate conformance of XML instance documents with these conceptual models.

28、 XSD XML Schema Definition 5.2 Namespaces XML namespaces defined in this document have URIs that follow the pattern: http:/ /standards.iso. org/iso/19157/-2/xxx/N.M, where xxx is the namespace abbreviation, N is the major version number, and M is the minor version number. The namespace directories i
29、nclude descriptions of the content of the namespace, and links to the base specification it implements and to the normative XML schema location. The following conventions are used to abbreviate the namespaces used to group XML elements. Definition of namespaces specific to the implementation of ISO
30、19157 and their rationale are discussed in 6.3. Table 1 includes namespaces that are from schema defined in other specifications and are imported by this implementation. The short string in the left column of Table 1 is used as a prefix to associate an XML element with the namespace. The second colu
31、mn contains an English-language description of the namespace, and the string in the third column is the URI that identifies the namespace. The final column lists the standard from which this namespace is imported. Table 2 lists abbreviations and other information for namespaces used for UML packages
