>Unfortunately code like this might well perform *very* >badly for some implementations. Unfortunately, _any_ deletion is going to have severe performance impacts on some implementations of NodeList. Only the cleverest implementations are going to even attempt to keep track of precisely which subtrees have changed and minimize recalculation... and the work involved in tracking that is going to impact performance and/or memory requirements elsewhere in the implementation. I've drawn up an essay summarizing the recent discussion and sent it to Lauren, which is apparently the proper procedure for submitting contributions to the FAQ -- she runs them past the WG for sanity-checking before adding them to the document. Actually, this one's large enough that it may go into the tutorial (there's a tutorial?) instead. ______________________________________ Joe Kesselman / IBM Research Unless stated otherwise, all opinions are solely those of the author.
