DTML objects pass their DTML namespace implicitly to called DTML objects.

Therefore, the easiest way to pass parameters is:

   <dtml-let
      param1=value1
      param2=value2
      ...
   >
     <dtml-call|var dtmlObject>
   </dtml-let>


Alternatively, you can call "dtmlObject" explicitely:

   <dtml-call|var expr="dtmlObject(_.None,_,param1=value1,param2=value2)">

Do not forget to pass "_.None,_". There are essential (in some
circumstances).
