* \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.
