 * \brief Registry of Predefined Result Type Classes
 *
 * A result class number is an unsigned 16 bit number.  Each class may
 * contain up to 65536 results.  A result code is formed by adding the
 * result number within the class to the class number multiplied by 65536.
 *
 * Classes < 1024 are reserved for ISC use.
 * Result classes >= 1024 and <= 65535 are reserved for application use.
