rss enclosures support in rss feed ?

I’ve just been messing around with NetNewsWire 2beta10 and love the rss enclosures feature for having file downloads revealed (and easily downloaded from the rss feed)

I was just wondering if there was any way to handle rss enclosures in the current wp-rss2.php (or is it a matter of merely having the enclosure tag set up in the text of the post properly ?)
