[LC1.1] 11.8 The header Element

LC comment on 
http://www.w3.org/TR/2007/WD-xforms11-20070222/#submit-header

Section states: "The submission element can contain zero or more header 
child elements, which must appear immediately after the optional resource 
and verb elements."

What happens when this occurs:
  <submission>
    <resource>...</resource>
    <header>...</header>
    <verb>...</verb>
    <header>...</header>
  </submission>

Should this dispatch some fatal error?
Should the <verb> be ignorred?
Should the first <header> be ignorred?

Why is this order important?  I can possibly see how resource and verb may 
conflict but not sure about header.

This comment also indirectly applies to 11.6 <resource>, which states 
"first child of submission" and 11.7.2 verb element, which says 
"immediately after optional resource element".  As far as handling of 
these items if out of order.
