ISO/IEC TR 9573-11 2nd edition provide XML and SGML DTDs for authoring and distributing ISO standards documents.
In addition the TR 9573-11 includes style specifications for all the elements defined by the DTD. The styles are based on the ISO/IEC Directives and the style specifications are described by DSSSL (ISO/IEC 10179) and XSL (Extensible Stylesheet Language 1.0). Using the style specifications, the XML (and SGML) documents based on the DTD can easily be rendered for printing, displaying, or creating PDF files by a DSSSL or XSL processor.
The XSLT specification in the TR provides a conversion to HTML from XML to make it possible to preview XML texts of standards by ordinary HTML browsers.
In the former days of TR 9573-11 1st edition, SGML texts of standards were mainly dealt with in the ISO office, where a specific formatter had only to work on a particular style specification. Today, however, XML texts of standards can be created by editors, interchanged within drafting groups, forwarded to secretariat and distributed to users of the standards. In such distributed environments, style formatting is required by all the people involved and the rendered styles should be preserved in document distribution. Here the standardized style specifications are essential and the TR 9573-11 2nd edition can contribute for a number of standards users.
