[Zope] Unless not quite the opposite of if?

Sorry!
But some problem reports are difficult to believe.

I tried the following DTML-method with Zope 2.1.6:

<dtml-var standard_html_header>
<dtml-unless "0">should render<br></dtml-unless>
<dtml-unless "1">should not render</dtml-unless>
<dtml-unless "REQUEST.has_key('XXX')">should render<br></dtml-unless>
<dtml-call "REQUEST.set('XXX',1)">
<dtml-unless "REQUEST.has_key('XXX')">should not render</dtml-unless>
<dtml-var standard_html_footer>

It worked as expected.

No hint that "dtml-unless" could be faulty.
