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.
