Do I need to do both, or is this an either/or choice?
You don't need to add the cache dependency if the message only changes when the *.i18n.php or Messages*.php files change.

You should have a look at how tracking categories work in the core, see Parser::addTrackingCategory(). It's not necessary to add any text to the page if there's a parser function on the page, the parser function can register the category directly in the output object. -- Tim Starling _______________________________________________ Wikitech-l mailing list [email protected] https://lists.wikimedia.org/mailman/listinfo/wikitech-l
