The "Document Layer" exisit for usability reasons, it gives a feature based view on the document model. One feature consists of one or more ODF elements (e.g. table). NOTE: Since ODFDOM 0.8.8, the "Document Layer" was marked as "Deprecated". We suggest you use Simple API replace the APIs in this package. Simple API is similar with it, but more stable and with more powerful features. More detail information, please reference the Javadoc in each class.
