Soft error can be returned by intrinsic methods (EnumerateInstances, GetInstance, etc.) to help distinguish between a query with no results (no error) and a query that failed for a specific reason.

'The CIM status code that characterizes this instance. This property defines the status codes that MAY be return by a conforming CIM Server or Listener. Note that not all status codes are valid for each operation. The specification for each operation SHOULD define the status codes that may be returned by that operation. The following values for CIM status code are defined: 1 - CIM_ERR_FAILED. A general error occurred that is not covered by a more specific error code. 2 - CIM_ERR_ACCESS_DENIED. Access to a CIM resource was not available to the client. 3 - CIM_ERR_INVALID_NAMESPACE. The target namespace does not exist. 4 - CIM_ERR_INVALID_PARAMETER. One or more parameter values passed to the method were invalid. 5 - CIM_ERR_INVALID_CLASS. The specified Class does not exist. 6 - CIM_ERR_NOT_FOUND. The requested object could not be found. 7 - CIM_ERR_NOT_SUPPORTED. The requested operation is not supported. 8 - CIM_ERR_CLASS_HAS_CHILDREN. Operation cannot be carried out on this class since it has instances. 9 - CIM_ERR_CLASS_HAS_INSTANCES. Operation cannot be carried out on this class since it has instances. 10 - CIM_ERR_INVALID_SUPERCLASS. Operation cannot be carried out since the specified superclass does not exist. 11 - CIM_ERR_ALREADY_EXISTS. Operation cannot be carried out because an object already exists. 12 - CIM_ERR_NO_SUCH_PROPERTY. The specified Property does not exist. 13 - CIM_ERR_TYPE_MISMATCH. The value supplied is incompatible with the type. 14 - CIM_ERR_QUERY_LANGUAGE_NOT_SUPPORTED. The query language is not recognized or supported. 15 - CIM_ERR_INVALID_QUERY. The query is not valid for the specified query language. 16 - CIM_ERR_METHOD_NOT_AVAILABLE. The extrinsic Method could not be executed. 17 - CIM_ERR_METHOD_NOT_FOUND. The specified extrinsic Method does not exist. 18 - CIM_ERR_UNEXPECTED_RESPONSE. The returned response to the asynchronous operation was not expected. 19 - CIM_ERR_INVALID_RESPONSE_DESTINATION. The specified destination for the asynchronous response is not valid. 20 - CIM_ERR_NAMESPACE_NOT_EMPTY. The specified Namespace is not empty. 21 - CIM_ERR_INVALID_ENUMERATION_CONTEXT. The enumeration context supplied is not valid. 22 - CIM_ERR_INVALID_OPERATION_TIMEOUT. The specified Namespace is not empty. 23 - CIM_ERR_PULL_HAS_BEEN_ABANDONED. The specified Namespace is not empty. 24 - CIM_ERR_PULL_CANNOT_BE_ABANDONED. The attempt to abandon a pull operation has failed. 25 - CIM_ERR_FILTERED_ENUMERATION_NOT_SUPPORTED. Filtered Enumeratrions are not supported. 26 - CIM_ERR_CONTINUATION_ON_ERROR_NOT_SUPPORTED. Continue on error is not supported. 27 - CIM_ERR_SERVER_LIMITS_EXCEEDED. The WBEM Server limits have been exceeded (e.g. memory, connections, ...). 28 - CIM_ERR_SERVER_IS_SHUTTING_DOWN. The WBEM Server is shutting down. 29 - CIM_ERR_QUERY_FEATURE_NOT_SUPPORTED. The specified Query Feature is not supported.'
'A free-form string containing a human-readable description of CIMStatusCode. This description MAY extend, but MUST be consistent with, the definition of CIMStatusCode.'
'This field is the message displayed to the user. %1 should be replaced with the corresponding storage provider's Name field. %2 should be replaced with the error message.'
'A string defining "Other" values for ErrorSourceFormat. This value MUST be set to a non NULL value when ErrorSourceFormat is set to a value of 1 ("Other"). For all other values of ErrorSourceFormat, the value of this string must be set to NULL.'
