        If you use a path expression to render a DTML object, it will
        pass a namespace with 'request', 'here', and the template's
        variables already on it.  This means that the DTML object will
        be able to use the same names as if it were being published in
        the same context as the template, plus the variable names
        defined in the template.

           ??
           i thought it will pass the "request" object as mapping, the "here" object as client and maybe the templates
           locally defined names (both local and global) and zopes calling mechanic will construct the DTML "_" under
           namespace from that?
           what did i miss? blf
