OK, how about: if the document element is an <html:html>, we choose the 
first <html:title> in document order; if the document element is an 
<svg:svg>, we choose the first child <svg:title> of the document 
element; otherwise, null.

This still is going to produce "incorrect" results for things like:

   <!DOCTYPE html>
   <svg>
     <foreignObject>
       <title>blah</title>
     </foreignObject>
   </svg>

but arguably you shouldn't be using <title> in there anyway.
