The CDDLM Configuration Description Language (CDL) is an XML-based language for declarative description of system 
configuration that consists of components (deployment objects) defined in the CDDLM Component Model. The Deployment API 
uses a deployment descriptor in CDL in order to manage deployment lifecycle of systems. The language provides ways to 
describe properties (names, values, and types) of components including value references so that data can be assigned 
dynamically with preserving specified data dependencies. A system is described as a hierarchical structure of components
. The language also provides prototype-based template functionality (i.e., prototype references) so that the user can 
describe a system by referring to component descriptions given by component providers. .
