These are template specific (ie. different for DTML and PageTemplates). 
For DTML this eg. could be:

     template(client=self, REQUEST=self.REQUEST, foo=bar, spam=egg)

foo and spam are additional (optional) keyword args you might want to 
pass to the template

In lib/python/OFS/DTMLMethod.py , see DTMLMethod.__call__() for details
