Maybe, you should state concisely from what context you want to
pass parameters to DTMLFile methods:
DTMLFile objects behave identically in this respect to
DTML methods!
* When called from ZPublisher (i.e. from the Web),
ZPublisher provides the object, the DTML is called for,
as "client" and "REQUEST" as "REQUEST".
* When called from DTML or Page Templates, "None"
is passed as "client" and a DTML namespace as "REQUEST".
* When you call it from either a Python method in your product,
from an External Method or from a Python Script,
you must pass sensible values for the two
positional parameters "client" and "REQUEST".
Often this is "self" and "self.REQEUST" (respectively
"context" and "context.REQUEST", in a Python script).
