053 * The optional GetDomain operation is used to obtain runtime information about
054 * the range of values of a metadata record element or request parameter. The
055 * runtime range of values for a property or request parameter is typically much
056 * smaller than the value space for that property or parameter based on its
057 * static type definition. For example, a property or request parameter defined
058 * as a 16bit positive integer in a database may have a value space of 65535
059 * distinct integers but the actual number of distinct values existing in the
060 * database may be much smaller.
061 * <p>
062 * This type of runtime information about the range of values of a property or
063 * request parameter is useful for generating user interfaces with meaningful
064 * pick lists or for generating query predicates that have a higher chance of
065 * actually identifying a result set.
066 * <p>
067 * It should be noted that the GetDomain operation is a "best-effort" operation.
068 * That is to say that a catalogue tries to generate useful information about
069 * the specified request parameter or property if it can. It is entirely
070 * possible that a catalogue may not be able to determine anything about the
071 * values of a property or request parameter in which case an empty response
072 * should be generated.
