The descriptor TA specifies the member type and the valid convention for that type. In the case of a user type the supertype can be set instead. TA can be used to assign an administration privilege to a type and to set the allowable storage mode for members of the defined type. A type-wide borrowing mechanism can be initialized (see "LA (Library Attributes)").
