This variable affects the behavior of XML Extensions during export. When set to 1 (on, true, yes), each nesting level of the output will be preceded by a newline and indented by two spaces for each level of the nesting depth.
When set to 0 (off, false, no), the exported data is written on a single line following the XML header line. Exporting in outline form makes the output more readable, but introduces additional characters in the output (which might be an issue when transferring the XML across a network). Some consumers of the XML might have issues with the inserted whitespace in the containing elements when the export is done with this configuration variable set to1 (on, true, yes). When XML Extensions is the consumer of the exported XML, newlines are stripped from the imported data and the additional spaces in containing elements are distributed to FILLER items, if any, in the import target data structure in the COBOL program; thus there is generally not an issue with outline export when XML Extensions is the consumer.
