The spec says [1] "The select expression is only evaluated when its actual value is needed by an instance of the step type being declared." That puts a pretty substantial burden on an implementation! Did we really mean to say that???!!!! But given it says that, the answer to your question is "no, no error, since the 'notUsed' option is never needed by any instance of the step".
