Chris has a point, but my intention was to make the production easier to read 
(benefits the user), not write (benefits the writer).  I've been wading through 
a lot of specs recently and I tend to appreciate anything that simplifies them.  
Maybe I'll change my tune when I'm further along the learning curve, but right 
now, the added flexibility on an instruction I won't use much (even if all my 
XML documents use namespaces) isn't worth the added complexity.
