Creating a Flow Service from an XML Document, DTD, or XML Schema
You can create a flow service based on the structure of a source file, such as an XML Schema definition, DTD, or XML document to automatically generate a service that receives an XML node as input. When creating a flow service this way, Designer generates IS document types, associated schemas, and an XML node based on the source file you provide. Designer adds the XML node as input to the flow service and creates references to the IS document types in the flow service output signature.
Important: The flow steps produced by this option are no different than those produced by manually inserting INVOKE pub.xml:loadXMLNode and INVOKE pub.xml:queryXMLNode steps in a flow service. After Designer inserts the set of default steps into your flow service, you can edit the default steps and insert additional steps just as you would any ordinary flow service.
