%block-display-noalt.class; Display Class No Alternatives Elements

The same content as the block display class parameter entity (%block-display.class;) minus the <alternatives> element. This parameter entity is used for a graphic or other image-related element, whenever the use of the ordinary block display class parameter entity (%block-display.class;) would cause a duplication or where alternatives are not allowed.
