Taken from the Zope-Book:
http://zope.org/Documentation/Books/ZopeBook/2_6Edition/ScriptingZope.stx

"""Note that DTML Methods and Documents take optional client and REQUEST 
parameters. If a client is passed to a DTML Method, the method tries to 
resolve names by looking them up as attributes of the client object. By 
passing our context as a client, the method will look up names in that 
context. Also, we can pass it a REQUEST object and additional keyword 
arguments - the DTML Method will first try to resolve names in them."""

Use <dtml-var expr="mymethod(None, _)">
