[description snipped]

This sounds very similar to XMLWidgets, VisualZope and ZIE.  A few
extensions to the behaviour system as described by you which may be
useful:
	* Add XMLWidgets Events to allow the Behaviour to be changed via
the user clicking on an item in the browser
	* Add Javascript Behaviour code to allow Events to operate
transparently accross the JavaScript/DTML boundary.
	* You will need a final rendering stage due to problems in Zope
namespace conflicts.  If you wish to utilise the ID property within an XML
document you will need to rename it to CID and apply a text transformation
to convert it to ID.
	* Why not allow multiple behaviours?  For example, an XSFT
transform to apply corporate styles, a DTML ZDOM transform for custom
javascript and a few others to make some objects "Active".  For example:

	<mydoc>
	  <item behaviours="draggable, resizeable, event=GotoPagexx"/>
		^^^^^^^^^ inherited from Behaviour objects in the
aquisition path
	</mydoc>
