I've tried hard to avoid using phrases that have any temporal connotations, i.e. any suggestion that one thing is done before doing another thing. I think you have read a temporal meaning into the word "prepended" that wasn't intended. There isn't actually a problem for implementations: if you say <a b="c"> <d/> </a> then the b="c" is evaluated first to produce a sequence X containing an attribute node, the sequence constructor <d/> is evaluated to produce a sequence Y containing an element node, and the two sequences X and Y are concatenated (i.e. X is prepended to Y). We should try to find a better way of saying it, but finding the right words isn't easy. Michael Kay
