This attribute indicates the download status.
If it is inactive, no download is in progress. This is the value
required in order to issue a Start command.
If it is inProgress, the download procedure has begun. This process
starts from the time a Software Distribution Site (SDS) login is
attempted and continues through the time during which files are
actually being transferred.
If it is stopping, a user has requested a stoppage but the connections
have not yet been completely torn down.
