The subsumes representation attribute lets you specify which Data Marking overrules another, even if they belong to different categories. For example, if you specify that the Data Marking Secret subsumes the Data Marking For Official Use Only, and then perform Sensitive Element Redaction, removing elements marked as For Official Use Only will also remove those marked as Secret, but not vice versa. 

During (2026x Refresh1) Sensitive Element Redaction or its preview, if the Data Markings' Category is ranked, higher-ranked Data Markings are treated as subsuming lower-ranked Data Markings.
