This section describes how to create a compound data type.
A compound type represents a business object that consists of two or more business objects. For example, a contact information object might consist of several business objects, including address, e-mail address, and a phone number; therefore, the contact information object is a compound type. In UDTT, there are two compound types: KColl and IColl.
