If the items to be grouped are already sorted on the grouping key, then group-by and group-adjacent will produce the same result, but group-adjacent may be more efficient because each group can be processed sequentially as it is encountered, rather than having to build all the groups in memory before processing starts. In this case it's simply taking advantage of the fact that you're already done the sorting and don't need to do it again. Michael Kay http://www.saxonica.com/
