Thanks, Martijn, that works.
however, if I now run this it crashes:
<dtml-tree content branches_expr="objectValues(['Folder', 'DTML
Document'])" sort=order >
<dtml-if expr="meta_type == 'Folder'">
	<dtml-var title_or_id>
<dtml-else>
	<dtml-if expr="id() == 'cnart'"><dtml-var cnartgif></dtml-if>

But I know it works because if I replace <dtml-var cnartgif> with boo
the boo shows up.  The image cnartgif is in the content folder. 
Here's the last 3 items in the traceback:

I have no idea what a 'childless decoration' is.
