The BusinessApplication element defines the format of all the entities (items) that a BA diagram can contain, and their dynamic properties.

Unlike the Form and Business Record formats, the Item elements in this file do not modify the behavior of an existing item, they create new item definitions with new names, inheriting from a default item. The items are Program, Form, Zoom, ReportData, WebService and WebServiceServer. This format is similar to the BusinessRecord, except there is no File element.
