/**
* The <i>Meta Box</i> contains descriptive or annotative metadata. The
* <i>meta</i> box is required to contain a {@link ISO14496_Box_HDLR hdlr} box
* indicating the structure or format of the <i>meta</i> box contents. That
* metadata is located either within a box within this box (e.g. an XML box), or
* is located by the item identified by a primary item box.
*
* All other contained boxes are specific to the format specified by the handler
* box.
*
* The other boxes defined here may be defined as optional or mandatory for a
* given format. If they are used, then they must take the form specified here.
* These optional boxes include a data-information box, which documents other
* files in which metadata values (e.g. pictures) are placed, and a item
* location box, which documents where in those files each item is located (e.g.
* in the common case of multiple pictures stored in the same file). At most one
* meta box may occur at each of the file level, movie level, or track level.
*
* If an {@link ISO14496_Box_IPRO Item Protection Box} occurs, then some or all
* of the meta-data, including possibly the primary resource, may have been
* protected and be un-readable unless the protection system is taken into
* account.
