But 
javascript:alert(document.documentElement.getAttribute("attr").charCodeAt(1).toString(16)) 
alerts (hex) 20, i.e. a space.

Which is consistent with http://www.w3.org/TR/xml11/#AVNormalize (and 
http://www.w3.org/TR/xml/#AVNormalize), which are better references than 
the xml:space one from the original post.
