XML Integration Objects
The Integration Object type of XML is available within Siebel systems to represent externally defined XML documents, where the object's XML representation is compliant with the XSD or DTD supplied by your trading partner or external system. This type of integration object supports a representation of XML documents.
NOTE: Siebel XSD does not support the use of <import> and <include> elements and the <any> attribute. To implement the <import> or <include> functionality, place the schema definition into a single file.
