+Attributes
+----------
+
+For classes, modules and instances, the attributes in the structure correspond
+to the attributes of each kind of object. For functions, however, the
+attributes in the structure correspond to the default arguments for each
+function, if any.
+
+The two kinds of structure attribute should be accommodated by both groups of
+objects, since without a default argument section, classes and instances may
+not employ default arguments in their respective instantiator/__init__ and
+__call__ methods.
