Progress representation of temp-tables and ProDataSets as XML Schema

Note: The following information is advanced and optional. You do not need to understand any of this to successfully use the features described in this chapter.

The XML Schema for a temp-table consists of a complex type definition for the fields (a sequence of field definitions), followed by any index definitions. The XML Schema for a ProDataSet consists of a complex type definition for the member temp-table buffers (a sequence of temp-table complex type definitions) followed by any index and data-relation definitions. Progress provides XML Schema extensions in order to fully describe the definitions of the temp-table or ProDataSet in XML Schema.

By default, Progress XML Schema extensions are present in temp-table and ProDataSet XML Schema documents. If you do not want the Progress XML Schema extensions, set the min-xmlschema option on the methods to TRUE.
