Sure:

	<dtml-in expr="..." prefix=MyList>
	  <dtml-let folder="MyList_item"> <!-- this is the current folder
					       may be, there should be not "_"
	                                   -->
             <dtml-if "_.hasattr(folder.aq_explicit,'What you are lookin for')">
	         ....
             </dtml-if>
	  </dtml-let>
	</dtml-in>
