You aren't allowed to put a p:output on an atomic step. Is that really wrong? The WD says: "It is a static error (err:XS0029) to specify a binding for a p:output inside a p:declare-step for an atomic step." It also defines a binding: "A binding associates an input or output port with some data source." I guess I'm trying to figure out what "binding" means. Is there no difference between declaring an output port and binding it? IOW, is this binding? <p:output port="result"/> Or is this binding? <p:output port="result"> <p:pipe step="someStep" port="somePort"/> </p:output> It seems (to me) that it should be ok simply to declare that an output port exists, so long as I don't attempt to bind it with a p:pipe. Appreciating all the help!

You aren't allowed to put a p:output on an atomic step. Does Calabash miss that too? Sigh. Another day, another bug :-) The output port is part of the declaration of the p:compare step.
