It's because you've lost your namespace. If you do,

     <dtml-var standard_html_header>
     <dtml-with YYY>
       <dtml-var discuss>
     </dtml-with>
     <dtml-var standard_html_footer>

you should get what you want. Or,
<dtml-var "discuss(_.None, _)">

<dtml-var discuss> is equivalent to <dtml-var name=discuss>. When called
that way, a DTML method is automatically given the namespace. <dtml-var
expr="discuss(_.None, _)"> would be the syntax to make sure that the
namespace is passed in to the DTML method when calling as an expression.
