Aloha Andy, et al,

Use cases for alternates could be as follows:

1. Amazon.com page on a book with alternate versions, e.g.,

2. TED.com talks, which include links to mp4, zipped mp4 and itunes,
e.g., http://www.ted.com/index.php/talks/view/id/51

3. New York Times, which include links to single-page and print
versions of articles, e.g.,

In particular, I am seeking a solution that can deal with different
filetypes (audio vs. video) as well as content length.

Let me include part of the original post:

There hasn't been much lately regarding the 'alternates'
discussion[1]. It seems that in the HTML spec[2], 'alternate' is meant
as something the user can choose between, i.e., style sheets[3],
and/or something the browser can try and render in a given rank order,
i.e., objects[4]. The suggested use of <ol> for preference and <ul>
for no preference is clever[1].

(this example modified from the wiki entry[1])

<ol class="alternates">
 <li><a href="example.mp3" rel="enclosure alternate"
 <li><a href="example.wav" rel="enclosure alternate"
 <li><a href="example.mov" rel="enclosure alternate"
