Moveable Type allows you to create multiple templates for archives and content pages. I've used this capability to produce RSS 1.0 and RSS 0.92 feed for each of the categories I'm using. I've also created a template to build an OCS file listing all the various syndication channels that I've now got available.

Here's the template I've been using:
