The d4p_bibliosetBase element is the base element for parts of a bibliographic entry, such parts may be author name, title, and publication information. Again, it is not intended to be used but rather intended to be specialized from. It is an inline element.
This element specializes from the ph element. See d4p_simpleBiblioset for an example specialization.

Because this is only intended for use as a base for specialization, see the d4p_simpleBiblioentry for an example.
