The SUB_CATEGORY_METHODS category is used to associate method identifiers with subcategories. Any number of unique method identifiers may be associated with a subcategory. The method identifiers reference the full method definitions in the parent METHOD_LIST category.
The procedure that is identified as _sub_category_methods.method_id may be used to validate the subcategory identified as _sub_category_methods.sub_category_id. Subcategory validation may be required in instances where conditions are placed on the values of data items within the subcategory that are more restrictive than those associated with each component data item. A simple example of such a restriction would be a normalization restriction on the components of a subcategory. Any procedure referenced in this category must also be defined in the category METHOD_LIST.
