Hm, I would say it's a feature. In this way you can't override (and
possibly break) your invisible ZClass index_html by accident.

Yes. The simplest is to change the index_html in you ZClass to something
else (like default or something) and adjust the View method (under the
view tab) of the ZClass accordingly. This way your users could add an
index_html without clashing, but it won't show automatically. So the
default method in your ZClass should look something like:

<dtml-var standard_html_header>
<dtml-if index_html>
   <dtml-var index_html>
<dtml-else>
   your default content
</dtml-if>
  .
  .
  .

THis is untested, but I think it should work. If not, at least
conditional content is the way to go.
