Actually, you can come up with a delimiter of you put it on the other 
end, as in:

   &dtml.lower-name;
   &dtml.capitalize-name;

I will probably include this in Zope 2.1. This is *needed* for
URLs, as in:

  <a href="&dtml.url_quote-name;">

When you use a dot, then you won't get html_quote unless you ask
for it.  You'll also be able to combine things:

  &dtml.lower.html_quote-name;

The default will be to use html_quote, so (in the 
coming beta 6 release):

  &dtml-name; 

is equivalent to 

 <dtml-var name html_quote>
