That is consistent!
"unless" is equivalent to "if not".
When "if" evaluate to "true", "unless" will skip its body and
'if var' evaluates to "true", if "var" exists and has a (Python) true
Seems that your request really has a key 'parmName'.

The "FSSession.has_key('ReturnerID')" should of cause yield "false".
This means, the "dtml-unless" body is rendered.
