Introduction : Overview of SOAP Web services in OpenEdge : Standards supported by OpenEdge SOAP Web services : XML Schema
XML Schema
SOAP Web services generally use XML Schema to describe both simple and complex data for their applications. OpenEdge Web services use the XML Schema standard to describe both simple data types (scalar parameters) and complex data types (array, temp-table, and ProDataSet parameters) in the WSDL file. An ABL Web service client maps XML Schema constructs into both simple and complex ABL data types.
