Hi,

I was wondering how a [test case][1] was handled in the DOM. (One  
issue is that it is sent as text/html and not application/xhtml+xml  
so it might change the results.)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
	"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:dc="http://purl.org/ 
dc/elements/1.1/">
<body>
   This photo was taken by <span class="author" about="photo1.jpg"  
property="dc:creator">Mark Birbeck</span>.
</body>
</html>


For example with Camino Version 2007050909 (1.5Int)(Firefox engine),  
we get

DOCTYPE: html
   HTML xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns="http:// 
www.w3.org/1999/xhtml"
     HEAD
     BODY
       #text: This photo was taken by
         SPAN property="dc:creator" about="photo1.jpg" class="author"
           #text: Mark Birbeck

         #text: .

And with Safari Version 2.0.4 (419.3), we get

HTML xmlns="http://www.w3.org/1999/xhtml" xmlns:dc="http://purl.org/ 
dc/elements/1.1/"
   BODY
     #text: This photo was taken by
     SPAN class="author" about="photo1.jpg" property="dc:creator"
      #text: Mark Birbeck
     #text: .
     #text:


In both cases, we can't identify that there is RDFa in the document.  
The doctype being dropped.  Though a very interesting thing, if I add

       version="xhtml-rdfa"


<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
	"http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
       xmlns:dc="http://purl.org/dc/elements/1.1/"
       version="xhtml-rdfa">
<body>
   This photo was taken by <span class="author" about="photo1.jpg"  
property="dc:creator">Mark Birbeck</span>.
</body>
</html>

The DOM is in Camino for example.

DOCTYPE: html
   HTML version="xhtml-rdfa" xmlns:dc="http://purl.org/dc/elements/ 
1.1/" xmlns="http://www.w3.org/1999/xhtml"
     HEAD
     BODY
       #text: This photo was taken by
         SPAN property="dc:creator" about="photo1.jpg" class="author"
           #text: Mark Birbeck

         #text: .

It is also in Safari.
