CDS-defined attribute
A standard attribute that CDS associates with names. A specific CDS-defined attribute has the same meaning no matter what type of entry (clearinghouse, directory, object) it is associated with. However, different types of entries can have different CDS-defined attributes. For example, every CDS name has the CDS-defined attributes of Creation Timestamp (CDS CTS), Update Timestamp (CDS UTS), and Access Control Set (CDS ACS). In addition to those attributes, a soft link has unique CDS-defined attributes containing its expiration time and the name it points to.
