[Zope] <dtml-with> works from one directory but not another depending upon the directory name

[John Glossner]

I have a case where including a file works based on the name of the folder.

My directory looks like this:
   /
   /html/
   /News/

When I do 
   <dtml-with html>
        <dtml-var news_html>
   </dtml-with>

I get output as I would expect.

However, when I cut and paste this same file to the News directory and do
   <dtml-with News>
        <dtml-var news_html>
   </dtml-with>

I get the following traceback:
Traceback (innermost last):

Does anyone know why the same file should work with the html directory
and not the directory named News? Is News somehow a reserved word?

Thanks,
