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