fsreqCommandCommandGUID Property

A GUID identifying this particular XML command. If a command fails due to a communication failure the client has no way of knowing if it has been processed. Each command that makes changes (as opposed to just retrieving data) will check the CommandGUID against the GUIDs that have already been processed. If the GUID has already been processed then it will not be re-processed and instead return with an error. This allows the client to saftely re-try a failed command without risking unintended changes.
