  Hum, there isn't really a way around this. I don't think making namespace
callbacks before the element start is any better. 
   if you get an events flow of
     startElement(foo...)
     namespace(ns...)
     startElement(bar, ns,...)
     attribute(href...)
     endElement(bar, ns,...)
     endElement(foo...)

you really expect 
     <foo xmlns:ns=...><ns:bar href=.../></foo>
   and not
     <foo><ns:bar xmlns:ns=... href=.../></foo>

  I think this would make scope detection more complex too.
This "use before declaration" is a property of the XML serialisation
