Choice group components
A Choice group can have both items and groups as components. A partitioned Sequence group can only have group subtypes.
Components of a Choice group must be distinguishable from each other. The components of a Choice group cannot have a component range other than (1:1). Only one component of a Choice group built in the output data.
A Choice group data type is only one of the group components. For example, the data type Record is a group type with a Group Subclass of Choice. The group type Record has three components: Order, Invoice, and Sales. The data validation of Record will be only one of the components: Order, Invoice, or Sales. For this reason, the components of a Choice group must have a component range of (1:1).
