[Zope] Automatically including another document

[Bruce Eckel]

Works well. Now, can I test for existence of the included document?
The following produces an "excessive recursion" error:

<dtml-let thisid="getId()">
   <dtml-with book>
     <dtml-if "_[thisid]">
       <dtml-var "_[thisid]">
     </dtml-if>
   </dtml-with>
</dtml-let>
