+=item * apply_params(\%role_params)
+
+Creates a new RoleSummation role application with C<%role_params> and applies
+the composite role to it. The RoleSummation role application class used is
+determined by the composite role's C<application_role_summation_class>
+attribute.
+
+=item * reinitialize($metaclass)
+
+Like C<< Class::MOP::Package->reinitialize >>, but doesn't allow passing a
+string with the package name, as there is no real package for composite roles.
