+        The building blocks are atomic RDCs, which collect a single piece of
+        user information. Examples are <b>&lt;rdc:date&gt;</b> or <b>&lt;rdc:isbn&gt;</b>.
+        Composite RDCs may collect multiple pieces of user information. This
+        is usually done by leveraging the functionality of existing RDCs.
+        A composite has its own data model, and makes the collected pieces
+        of information available in a structured form to the application.
+        An example of a composite RDC is <b>&lt;rdc:dateRange&gt;</b>.
+        Within the RDC framework, a component is a generic term, referring to
+        either an atomic RDC or a composite RDC. Finally, a container is a
+        helper tag used to aggregate multiple RDCs into a single coherent
+        unit with respect to the task at hand and the associated dialog. It
+        also defines the dialog management strategy. The most commonly used
+        container is <b>&lt;rdc:group&gt;</b>. Various group dialog management
+        strategies are supported and additional ones can be plugged in.
+        A simple directed dialog, a rule-based strategy and an SCXML-based one
+        are available.
