     * <p>This is the method to overide when you want your container
     * to provide these kinds of attributes. By default this method will set
     * 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.
