This International Standard specifies the semantics and syntax of DXL. DXL is a language for exchanging
tree-structured charts among CASE tools.
DXL is applicable to:
1. exchanging ISODEC 863 1 compliant tree-structured charts (examples of which are shown in annex A
(informative) of ISO/IEC 863 i);
2. exchanging program flowcharts defined in ISOíIEC 5807 if they are weil-structured and don't have data
defined in ISO/IEC 5807; and
3. describing procedure oriented algorithms.
This International Standard does not specie:
1. graphical information about a chart, such as the shape, size, and location of symbols;
2. configuration information of a chart, such as its version, author, and file name; or
3. information about the data used in the algorithm described by DXL, such as its structure, reading and
writing, and declaration.
