Is a conforming implementation required to signal an error when an argument not defined by the standard occurs in the lambda list of a function?

I'm not a language lawyer, but I'd be /very/ surprised if it where in the spirit of the ANSI spec that you could "extend" functions at your whim. As a data point, look at the dictionary entry for DIRECTORY which specifically allows implementations to add keyword parameters to the function. Why would that passage be in there?
