This object identifies the resource owner sub-type for which
threshold is configured.
For example, 'processor' and 'io' are sub-types of the
'memory' resource owner. Each resource owner sub-type may
have different threshold configuration. If the resource owner
does not have any sub-type, then value of this object would
be zero. This object indicates the 'cermResOwnerSubTypeId'
value (in the cermResOwnerSubTypeTable) for the corresponding
resource owner sub-type.
