Rendition Markup Plus
Names a mix of the simplest of the typographic emphasis elements, as well as those for subscript and superscript, for use in models allowing data characters and this restricted mixture.
Implementor’s Note: This parameter entity and the related parameter entity %just-rendition; have been put in place to restrict the amount of variability a person can achieve when modifying the Tag Set through parameter entity redefinition in the DTD. Some elements have been set as #PCDATA plus one parameter entity, while others have been set to #PCDATA plus the other, in an effort to allow designers to modify entire groups of elements, but not change similar models individually.
