Content model for the <graphic> element
This is a very permissive model, allowing almost anything that could be inside a full Figure. In most cases, the <graphic> element will be empty, with attributes pointing to an external file.
<!ENTITY % graphic-model
"(%access.class; | %address-link.class; |
%id.class; | %label.class; |
%caption.class; |
%display-back-matter.class;)* " >(alt-text | long-desc | email | ext-link | uri | object-id | label | caption | attrib | permissions)*
