BTW, my test was flawed. Safari/WebKit handles this content as it  
should and is interoperable with the other XHTML UAs. In other words  
these visual UAs display the image and ignore the contents of the XML  
element.

As others have pointed out, they do not provide the contents of the  
element as fallback for a bad URL.

This forking of fallbacks also accompanies a bigger issues of lossy  
conversion between serializations.

Finally, no tests have been made of any aural and tactile UAs to see  
if they can discover the fallback content.

Take care,
