Um... "eek!"

When phrased that way, it seems like a very un-XML approach to things.

It strikes me that the MIME fallback approach might be something to  
keep in mind. A simple container of multipart/mixed, then a list of  
possible alternatives in order of preference.

My guess of how that would translate in this case:

<try>
     <text name="rendered text" >
         <content>some text</content>
     </text>
     <projection src="data/text_fallback.png" />
</try>
