//@PURPOSE: Provide Value-Semantic Type for an open queue operation status
//
//@CLASSES:
// bmqa::OpenQueueStatus: value-semantic type for an openQueue result
//
//@DESCRIPTION: This component provides a specific value-semantic type for the
// result of an open queue operation with the BlazingMQ broker, providing
// applications with the result and context of the requested operation.
//
// A 'bmqa::OpenQueueStatus' type is composed of 3 attributes:
//: o !result!: indicates the status of the operation (success,
//: failure, etc.) as specified in the corresponding
//: result code enum, 'bmqt::OpenQueueResult::Enum'
//: o !queueId!: queueId associated with the open queue operation
//: o !errorDescription!: optional string with a human readable description of
//: the error, if any
// BMQ
