FilterDescriptor objects are used to provide semantic information about parameters required for external system APIs. For example, if a external system API needs parameters for ageLimit and wildcardName, it would be inappropriate to show these in this level, because it would expose the implementation. But it is still important for the next level to know that a name is wildcard-enabled (among other things), so that it can put up a specialized dialog box (such as starts with, contains, ends with). A FilterDescriptor can be used in this case to indicate that a parameter has additional meaning that cannot otherwise be revealed without unmasking the implementation.
