Elements that can be included along with data characters inside the content model of the <volume-series> element
Design Note: All inline mixes begin with an OR bar; since %just-rendition; is an inline mix, the OR bar is already there, or %just-rendition; is itself a null string, and the OR bar need not be added to %volume-series-elements;.
<!ENTITY % volume-series-elements "%just-rendition; " >
