public final class Document
extends AbstractResourceEnvironmentGroupContainer

The document is the highest level of the MO:DCA data-stream document component hierarchy. Documents can be made up of pages, and the pages, which are at the intermediate level, can be made up of objects. Objects are at the lowest level, and can be bar codes, graphics, images, and presentation text. At each level of the hierarchy certain sets of MO:DCA data structures, called structured fields, are permissible. The document, pages and objects are bounded by structured fields that define their beginnings and their ends. These structured fields, called begin-end pairs, provide an envelope for the data-stream components. This feature enables a processor of the data stream that is not fully compliant with the architecture to bypass those objects that are beyond its scope, and to process the data stream to the best of its abilities. A presentation document is one that has been formatted and is intended for presentation, usually on a printer or display device. A data stream containing a presentation document should produce the same document content in the same format on different printers or display devices dependent, however, on the capabilities of each of the printers or display devices. A presentation document can reference resources that are to be included as part of the document to be presented.
