Yes, the DOM Consistency issue would disappear if, and only if, also the XHTML side used @prefix instead of @xmlns:ADCD. (It would leave the problem that prefix-based indirection in itself confuses people--sometimes in bug-inducing ways. See for example: http://lists.xml.org/archives/xml-dev/200502/msg00306.html http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6475032 http://dev.ctor.org/soap4r/ticket/179 http://sourceforge.net/tracker/?func=detail&atid=454391&aid=924041&group_id=48863 ) -- Henri Sivonen hsivonen@iki.fi http://hsivonen.iki.fi/
