Hi Folks, (d) (As with all performance questions). It's not even a simple answer if you know the processor. Saxon will sometimes detect that appending to a sequence can be done without copying, either because the old sequence will never be used again, or because both can share the same storage - and even I find it difficult to predict the circumstances in which the optimizer will determine that such optimizations are feasible. Also, of course, cost is not one-dimensional: time and space both need to be considered. Michael Kay Saxonica
