Could you explain > why you would test if an attribute is absent? For foreign attributes it would make a difference. You may also wish to know so you can do your own serialization of an element. I can't say it is the most useful thing in the world, but it is not useless either, and I think adding it would not be a large burden on implementors. Regards, Maciej
