This example will cover the customization for Soft type attributes as well.

Consider the example:

Windchill ESI is configured to send the Soft type extension of “wtPart” as “BuyerPart” where BuyerPart contains all elements as wtPart and one extra element called “Buyer” as soft attribute. Windchill ESI user can now create either Part or BuyerPart. ESI response may contain either Part and/or BuyerPart inside AddedPart or ChangedPart or UnchangedPart element.
