- @param Value Describes the current status of a hardware or software entity. \r
- This includes information about the class and subclass that is used to classify the entity \r

- A system may contain multiple entities that match a class/subclass pairing. \r
- The instance differentiates between them. An instance of 0 indicates that instance \r
- information is unavailable, not meaningful, or not relevant. Valid instance numbers start with 1.\r
- @param CallerId This optional parameter may be used to identify the caller. \r
- This parameter allows the status code driver to apply different rules to different callers.\r
