DLM functionality and fragments are most commonly defined in a file called, dlm.xml, which is located in the properties directory. The default dlm.xml file for 2.5.0 is shown below. Although no DTD or schema is currently used two top level elements are supported by the DLM code: dlm:property and dlm:fragment. As of uPortal 3.1.0, it is also possible to define DLM fragments in the portal database (see below).
