    //		<foo>

    // element, and the names must match. BUT the tricky bit is that the closing
    // element will be read by the child.
    //
    // 'endTag' is the end tag for this node, it is returned by a call to a child.
    // 'parentEnd' is the end tag for the parent, which is filled in and returned.
