Dave Winer has produced "Guidelines for more powerful OPML". Highlights
include:

"If an element is pointing to a feed, set its type to "rss". Do this even if
it's not an RSS feed."
...
"...most of our code...assumes if the extension is not .opml that the file
is not OPML"
...
"please consider putting a real email address in ownerEmail... If you're
creating a hierarchy to be included in other people's hierarchies, it can't
work without these two bits of information"
...
"Read this RFC"

Here's the RFC :
[[
A subscription list is a valid OPML document.

Each <outline> element in a subscription list has, at minimum, the following
attributes: text and xmlUrl. Text is the name of the feed, usually derived
from the <title> element of the RSS <channel>. xmlUrl is the Web address of
the feed.

Subscription lists may contain hierarchy. Processors must preserve
hierarchy, even if they don't use it, so that lists that contained hierarchy
on import contain the hierarchy when exported. When hierarchy is used, the
outline elements designating a category must have a text attribute and must
not have an xmlUrl attribute
]]


Personally I'd advise using a different format altogether. Any.

Cheers,
Danny.
