ResponseStatusCode indicates if the operation succeeded or failed, and if it failed - why. ResponseStatusText is a textual description of ResponseStatusCode. For all operations the set of response codes must be defined. The actual set is dependent upon the context.
The following codes are defined:
- "OK": Operation succeded.
- "ERR99": Other error. "statusText" should describe the error.
Other codes, if necessary, are defined where ResponseStatus is used.
