With this command you can query extended information to a specific backorder.
command = StatusDomainApplication application = (APPLICATION ID)
NOTICE:
Since there is the possibility that there exist multiple backorders to one domain name, this command needs to use the APPLICATION ID instead of the domain name to provide a unique result. The application ID of a backorder can be obtained by listing the backorders (see Query Domain Backorder List).
