{
{   The purpose of this request is to allow a set owner, operator, system
{ administrator, or volume management to change the permission to access
{ an active set (for access purposes, a set with any volume active.) .
{ If access status is stc$deny_access, volumes may still be added to and
{ deleted from the set, but no more jobs, other than those currently accessing
{ the set, will be allowed access to the set.  This option allows all
{ members of the set to be up, before any user can access the set.  This
{ also allows idling down of the set, by denying other jobs access. If
{ access status is specified as stc$allow_access, all permitted users may
{ access the set.
