External module in the base DTD Suite that defines the Phrase Class Elements elements that is, names the inline, subject-specific elements
At the time of this DTD’s creation, there were only two phrase-level elements. If more specific subject words (such as “gene”) are added to later versions of this DTD, they should be added to the %phrase.class; entity and defined in this module.
