I started on this, but ran into problems and think I understand why in XMLAda, variant records are used. The DOM standard contains some cirular dependancies. interface Node { ... readonly attribute Document ownerDocument; ... } interface Document : Node { ... } hmm, it could be easier than I thought since Document is mainly routines. At the time I looked at it I wasn't sure how to resolve the problem, but then I'm not experienced with software in any major way so the problem might be trivial and I just can't see it. I am going to return to it post exams... Chris
