/**
 * A container in DIDL content.
 * <p>
 * Note that although this container can have sub-containers, the
 * {@link org.fourthline.cling.support.contentdirectory.DIDLParser}
 * will never read nor write this collection to and from XML.
 * Its only purpose is convenience when creating and manipulating a
 * recursive structure, that is, modelling the content tree as you
 * see fit. You can then pick a list of containers and/or a list of
 * items and hand them to the DIDL parser, which will render them
 * flat in XML. The only nested structure that can optionally be
 * rendered into and read from XML are the items of containers,
 * never their sub-containers.
 * </p>
 * <p>
 * Also see ContentDirectory 1.0 specification, section 2.8.3:
 * "Incremental navigation i.e. the full hierarchy is never returned
 * in one call since this is likely to flood the resources available to
 * the control point (memory, network bandwidth, etc.)."
 * </p>
