Definition
A set of characteristics describing a transfer object group. Typically there can be multiple transfer object groups conforming to the same transfer object group type. PAIS requires that each transfer object type descriptor has at least one groupType element. Each groupType element may contain any number of additional groupType elements and an unlimited number of dataObjectType elements. These elements are convenient for modeling hierarchies such as directory structures. The groupType is specified in the XML schema and is of type transferObjectGroupType
