         * the following attributes:
         * <dl><dt>name<dd>The name of the child (it's identifier) -
         * String instance.
         * <dt>parent<dd>The parent of the child (ie ourself here) -
         * a ContainerResource instance.
         * <dt>url<dd>If a <em>identifier</em> attribute is defined, that
         * attribute is set to the full URL path of the children.
         * </dl>
