+usually provide only the least common denominator of functionality.  To
+empower roles further, more configurability than -alias and -excludes is
+required.  Perhaps your role needs to know which method to call when it is
+done processing, or what default value to use for its url attribute.
+Parameterized roles offer a solution to these (and other) kinds of problems.")
