%just-base-display-noalt.class;
Most Basic Display Elements
Just the few display elements that are simple display objects: a picture, a movie, a sound file.
Remarks
This parameter entity is normally the same as Most Basic Display Class Elements except for excluding the <alternatives> element, because that element is pulled into a content model via some other means.
