I'd keep the startTagClose Conversely, James Clark has written several serializers, e.g., XmlWriter in trang, in which the convention is: startElement* attribute* (text | startElement)* endElement No explicit end-start-tag is used or needed. The writer can tell when a start tag needs to end; in fact, the convention helps to produce empty element tags without backtracking. Use is simple and natural. Bob Foster http://xmlbuddy.com/
