Per the specification the element represents the text given by the alt  
attribute in the scenario that the image is not available and both the src  
and alt attribute are set. That the image is not available follows from  
the fact that the src attribute has a value that is an ignored  
self-reference which follows from the value being the empty string and  
supposedly (full document is not available here) the base URI being the  
same as the document's address.
