Related informationA property of mode Page, Value List, Page List, Value Group, or Page Group is known as an aggregate property. You can access a portion of an aggregate property to obtain a value or to set (assign) a new value. For example, for a Value List property, you can copy or alter the value of the tenth element. For a Page List property, you can add a new page at the end of the existing list of pages.
Use these notations and keywords to identify parts of aggregate properties. You can use these in reference directives, reference JSP tags, as parameters to the Property-Set method, and in data transforms. A few keywords such as <INSERT> are only valid in destinations — target property references.
