7 -- * Most specific range for org_unit and grp wins.
9 -- * circ_modifier match takes precidence over marc_type match, if circ_modifier is set here
11 -- * marc_type is first checked against the circ_as_type from the copy, then the item type from the marc record
13 -- * If neither circ_modifier nor marc_type is set (both are NULLABLE) then the entry defines the default
