When converting XML to a document (IData object), a complex type in the XML is represented in the IData object as a Document field. During the conversion while parsing the XML, Integration Server checks complex types for the xsi:type attribute. An xsi:type attribute specifies that the type in the instance document overrides the type definition that was defined in the schema. When Integration Server converts a complex type that corresponds to a derived type, it adds the *doctype field to the Document field in the IData object. Integration Server sets the *doctype field to indicate that the Document field is an instance of a derived type instead of the base type. Specifically, Integration Server sets the *doctype field to the fully-qualified name of the IS document type that corresponds to the value of the schema type name specified in the <xsi:type> attribute.

For example, a complex type in XML being converted might include the following:

When Integration Server generates the Document field for the invoice address, it will add a *doctype field and set its value to the fully-qualified name of the derived document type that corresponds to the schema type name “order:USAddress” (for example, orders:docType_Ref_order_USAddress).

When working with a Document field that was converted from XML, do not delete or edit the *doctype field.
