How to obtain the link/URL to the feed of a custom taxonomy?

What I need to accomplish is to provide a feed link for every item in a custom taxonomy. The function get_category_feed_link only works for categories, and I don’t see that tags support this either.

How to obtain the feed for a custom taxonomy item? Does exists something like get_taxonomy_feed_link(<your_custom_taxonomy_name>, <your_custom_taxonomy_item_id>).

Thanks!
