+    Composite component example.
+    This is a example of a composite component (the AcmeContainer class)
+    with parts that it manages.  The parts include a gizmo and widget    
+    component which are automatically resolved by the container and supplied
+    to the AcmeContainer component via the Parts constructor argument. 
+    Note that we are not including the Dimension arguments in the context
+    thereby demonstrating optional context entry semantic. A feature of 
+    this example is the usage of a reference element as the mechanisms
+    to wire the context 'widget' part into the context supplied to the 
+    'gizmo' component.  Wiring of dependencies is explicit and handled 
+    by the reference element within Gizmo's context.  The reference element
+    declares that the context entry for the key 'widget', supplied to 
+    Gizmo shall be the selected from the 'parts' of the enclosing component
+    using the name 'widget' (where the uri is in the form [scope]:[name] and
+    scope may be one of 'context' or 'parts' refering respectivly to the 
+    enclosing components parts or context).
