Content model for the <graphic> element
This is a somewhat permissive model, allowing a number of the elements permitted inside a full Figure. In most cases, the <graphic> element will be empty, with attributes pointing to an external file.
<!ENTITY % graphic-model "((%id.class;)?, (%access.class;)*, (%display-back-matter;)*) " >
((object-id)?, (alt-text | long-desc)*, (attrib?, permissions?)*)
