Selecting Source Object in the XSD Wizard

Each XML document has exactly one root or document element. The root element corresponds to the integration object. However, because an XSD or DTD file can be used by a vendor to specify the XML documents that it can generate, the root element cannot be inferred from the XSD or DTD file. For example, Ariba can generate XML for contracts, order requests, subscriptions, and so on. A single file describes the possible XML documents.

As a reference when determining the root element, use an XML document that best represents the XML documents you are integrating. The root element is the root of the XML hierarchy tree. No part of the root element appears within the content of any other element. For all other elements, the <Start></Start> tag appears within the content of another element.

To view any XML hierarchy, with collapsible and expandable elements, use an XML editor, an XML reader, or an XML-capable browser such as Microsoft Internet Explorer.
