Using only "forward" is insufficient -- a tree is 2-dimensional (this is why there are many possible traversal orders) and we use two independent axes -- "ancestor" and "preceding". Of course. :-> But what makes this traversal interesting and different is that instead of relying on XSLT's built-in traversal of child nodes collected as a node list, it explicitly steps forward one node at a time. In the default traversal, the forward part is implicit (and as you know, XSLT requires only that the result come out *as if* the nodes are traversed forward in document order). Since natural language rarely finds it practical to describe and specify all distinguishing characteristics of a given case, we usually encapsulate them by using a code or label that only hints at them -- and rely on context (as always) to disambiguate the rest. If the term sticks, it comes through use to denote all the particulars (because repeated use within a community of practice allows it to "carry its context with it"). Of course you know all this, which is why you asked for a native speaker's advice ... because what constitutes a good hint in a given case, before a term has established itself, is hard. Anyway, glad to help. Words are fun. Cheers, Wendell
