Yes that is correct, but the structure can contain over 1000 business items and the structure can be slightly different for each document that is produced.
The issue was I wanted type definitions for the entities.
So in XSD how would I say that this item, wherever it appears in the tree will always be a string?
<section id="name"/>

hi Neal,

what should i understand ?

"
-the section element must have an id attribute which value must be :
   -'report definition' if the host element is root
   -'officers' if the parent of the host element is identified with 
'report definition'
   -'secretary' if ...
   -'name' or 'appointment date' or ... if ...
"

is that your assertions ?
