Oops.. sorry for the confusion. My brain is fuzzy today. I was actually 
thinking of simply writing the URI, and then I thought I'd make it more 
'elegant'... i.e. the example should have been:

   The following URI demonstrates blurring:
	http://uri.org/effects.php?arg=blur&src=rose.jpg

No, not so nice (although I don't see why you put 'src=' there).
