+=head1 ALLOWING EXTRA PARAMETERS
+
+By default, any parameters not mentioned in the parameter spec cause this
+module to throw an error. However, you can have have this module simply ignore
+them by setting C<MX_PARAMS_VALIDATE_ALLOW_EXTRA> to a true value when calling
+a validation subroutine.
+
+When calling C<validated_hash> or C<pos_validated_list> the extra parameters
+are simply returned in the hash or list as appropriate. However, when you call
+C<validated_list> the extra parameters will not be returned at all. You can
+get them by looking at the original value of C<@_>.

By default, this module exports the C<validated_hash>,
=head1 IMPORTANT NOTE ON CACHING
-When C<validate> or C<validatep> are called the first time, the
-parameter spec is prepared and cached to avoid unnecessary
-regeneration. It uses the fully qualified name of the subroutine
-(package + subname) as the cache key. In 99.999% of the use cases for
-this module, that will be the right thing to do.
