This object indicates per user global current notification
severity for the resource owner sub-type and resource
user/group relationship.
For example, lets assume that total utilization of the
'processor' memory resource owner has exceeded the applied
per user global rising threshold value for *minor* severity
(and its utilization is still above the corresponding
falling threshold value), then current per user global
notification severity for the 'processor' memory and 'RU-1'
relationship would be 'minor'.
