A CATEGORY_GROUP_LIST Example

The following example of category_group_list illustrates the category groups that are defined in this DDL. These include the group of categories that define categories, the group of categories that define data items, and the group of categories that define the dictionary. An additional compliance group is also defined for categories that are included specifically for compliance with previous versions of DDL. Each of these category groups is defined as child of the group named ddl_group to which all of the base DDL categories belong.
