The idea is based on what HTML does with <object>, which works very well:

<http://www.w3.org/TR/REC-html40/struct/objects.html#h-13.3>

The user-agent is expected to use the first one in the tree that it's 
able to handle. At the bottom level is a text fallback that can be 
displayed when nothing else works; we already have <desc> for that.

Cheers,
Martin
