I disagree that BGPs do not evaluate variables (they take prior bindings, e.g. from nested elements, into account). Also my definition does not talk about replacement in BGPs, but only about injecting additional values into the stream of bindings that is used whenever an element is evaluated. I have no idea how to proceed here, as this dialog between myself and Peter seems to run in circles. Is there anyone else here in the WG who has problems with my current definition, e.g. implementers would not know what to do? Holger > > This may be only a matter of terminology.
