Make a subclass of CommonTree that contains the information fields you
need.
Change the option ASTLabelType=MyCommonTreeSubClass.
Element references are now to objects of your new type and you can add
the information you need.

But, you might really be wanting Heterogeneous tree nodes? See wiki
articles on this.
