ABL provides a set of XML Schema attributes to specify ABL properties that are extensions to basic XML Schema. These properties enable you to completely describe temp-table and ProDataSet definitions with XML Schema. A non-OpenEdge application that works directly with an OpenEdge-generated XML Schema will ignore these extensions. See Use XML Schema for more information.

These attributes allow temp-table and ProDataSet definitions to be fully restored when XML Schemas are read back into ABL. You can control whether some of the ABL XML Schema extensions are present in the XSD with options on the WRITE-XML( ) and WRITE-XMLSCHEMA( ) methods.
