Thread:Template talk:Extension/User rights documentation

I've created Category:Extensions which add rights. Currently, additional user rights are not documented anywhere, and this can be very confusing (see e.g. Extension:AbuseFilter) because you have to look for a wiki where the right is available and check Special:ListGroupRights. Hopefully, all rights descriptions are in Mediawiki:Right- messages, so I think that we could use the rights parameter to automatically list them with. To pass the list, we could either split the parameter in rights1, rights2 etc. or use the #titleparts "string parser & converter" (rights=name1/name2/name3 etc.); to add additional notes, I wonder if we should create a rightsnote1,2... or a single rightsnotes parameter.
