/**
 * A RecordDef is an ordered collection of Fields representing the structure of a
 * Record.
 *
 *
 *
 * Examples of RecordDefs include definitions of
 *
 *
 *
 *     language-specific data structures
 *
 *     database records
 *
 *     IMS segments
 *
 *
 *
 * The internal structure of a RecordDef instance is constructed by adding Field
 * instances as features (using the ElementOwnership association) and pointing
 * each Field instance?s inherited type reference to the Classifier instance
 * representing the Field?s data type. The referenced instance can be either a
 * primitive data type (an instance of DataType, such as "integer") or a
 * structured data type (such as a Group instance).
 *
 *
 *
 * Refer to the example for more details of the relationships between RecordDefs,
 * Fields, Records, and their values.
