[Zope] Rendering files with exception

| It seems that you would like to render "index.htm" if it exists
| in the current folder and do something else, otherwise.

Yes, but it is in my initial question. I am sorry, but I need to learn
english more (I know low word count).

| The following code is not completely safe but may be sufficient
| for your purposes:
|=20
|     <dtml-if "_.hasattr(aq_explicit,'index.htm')">
|       <dtml-var index.htm>
|     <dtml-else>....
|     </dtml-if>

Absolutelly sufficient and works :)

Why it is not completely safe?
