Attribute	Description
AppSpecInfo	For information on this property, see “Identifying business object

Cardinality	For relationship details between XML elements and cardinality, see
	Chapter 3, ″XML data handler,″ in IBM WebSphere Business Integration
	Adapters Data Handler Guide.

Special attribute values

Simple attributes in business objects can have the special value, CxIgnore. When it receives a business object from the integration broker, the connector ignores all attributes with a value of CxIgnore. It is as if those attributes were invisible to the connector. No XML is generated for them.

Because the i2 connector requires at least one primary key attribute to create a business object, you need to ensure that business objects passed in to the connector should have at least one primary key that is not set to CxIgnore.

Additionally, The i2 connector assumes that no attribute of business object type has a value of CxBlank. Simple (String) attributes with a value of CxBlank are included in an XML document. Empty double quotation marks (″″) in an XML document are used as the PCDATA equivalent of CxBlank.

Identifying business object application-specific information

Application-specific information provides the connector with application- dependent instructions on how to process business objects. If you extend or modify an application-specific business object, you must make sure that the application-specific information in the business object definition matches the syntax that the connector expects.

Application-specific information at the business object- level

The following table provides application-specific information at the business object-level for the wrapper business object supported by the i2 connector.

Parameter	Description
Port=	The name of the i2 port type for the operation.

Application-specific information at the attribute level

The following table provides application-specific information at the attribute level for the wrapper business object supported by the i2 connector.

Parameter	Description
Type=	The type represented by the attribute at the wrapper business object
	attribute level. The type could be input or output representing the input
	and output for the operation.
