What Is an XML Document Type?
When you create an XML document type from an XML schema definition, Integration Server creates a collection of assets to represent the XML schema definition, which can include:
XML document types, each of which corresponds to a global element declaration, global attribute declaration, or global complex type definition in an XML schema definition.
XML fields each of which corresponds to global element declaration with simple content.
IS schemas which contain the global simple type definitions for a particular namespace in the XML schema definition.
Like IS document types, XML document types can be used to define the structure of document being created from an XML node or a document being converted to XML, define service signatures, build a document or document list field, or perform data validation. However, XML document types more accurately represent XML Schema definitions and provide support for XML schema constructs/feature that are not supported through IS document types.
