It does not work, because <dtml-with Bill> renders "Bill" (leading to
a string which does not have an attribute "id").
It will work, when you use:

	<dtml-with "Bill">...</dtml-with>

Note the "...". They prevent automatic rendering.

This is an FAQ. You want computed variable access. You use
"_.getitem(...)" (if you want the object itself) or "_[...]"
(if you want a rendered result) for this.

Thus, if you want to process all owners, you could do:

	<dtml-in owners>
	  <dtml-let owner=sequence-item>
	    <dtml-with "_.getitem(owner)">
	      <dtml-var parseit>
	    </dtml-with>
	  </dtml-let>
	</dtml-in>
