I'm having problems working my head around the new 3.1 subcategories documentation.

I have entries from my portfolio site structured so that there are three Top-Level categories (About, Resume, and Work). Under Work, there are a half-dozen different subcategories.

On the individual archives that fall under the Work parent category, I would like to show the other subcategories (under Work) in a list. For what it's worth, I want to use these on dynamically-built pages.

Any ideas?
