The easiest way to do this, I think, would be to subclass
TypedCompositeActor and override the newRelation() method to
return a relation that contains the parameter you are interested in.
You would then want to create a new configuration that uses
your subclass rather than TypedCompositeActor.

When you delete a relation, then any attributes it contains
are automatically deleted, in the sense that there will be no
more references to them accessible from anywhere, so they will
be garbage collected. You shouldn't need to delete them explicitly.
As for when you right click on an actor, the following are all
subclasses of ptolemy.kernel.util.Attribute, and hence can be put
inside an actor to customize the GUI interaction for that actor
in various ways:
ptolemy.vergil.basic.NodeControllerFactory: An attribute that you
can subclass to determine what the GUI does when you right click
or double click on an actor. This is not all that easy to use,
but there are lots of examples of "Controllers" in ptolemy.vergil.
ptolemy.actor.gui.EditorPaneFactory: An attribute that you can put
in an actor to create a custom panel to be displayed when you
"Configure" the actor. That is, if you don't specify a
NodeControllerFactory, then by default double click invokes
"Configure" and right-click offers at least "Configure". What
"Configure" does can be customized by creating a subclass of
this attribute. This is much easier to use than creating
a custom NodeController.
ptolemy.actor.gui.InsideEntityEditorPaneFactory: A subclass that can
serve as an example.
ptolemy.actor.gui.TableauFactory: An attribute that can be subclassed
and placed inside an actor to customize what happens when you look
inside an actor. This one is also easy to use.
Hope this helps...
