A server which supports no quality information must return 3 (Good). It is also acceptable for a server to simply return Bad or Good (0x00 or 0xC0) and to always return 0 for Substatus and limit.
It is recommended that clients minimally check the Quality Bit field of all results (even if they do not check the substatus or limit fields).
Even when a ‘BAD’ value is indicated, the contents of the value field must still be a well defined VARIANT even though it does not contain an accurate value. This is to simplify error handling in client applications
