Just Paragraph Class Elements
The paragraph element and any other elements that need to occur anywhere a paragraph can be mixed with text. By default, this class is set to solely of the <p> element.
This parameter entity may be redefined by a customization to name any element(s) that the Tag Set wishes to be able to use anywhere within textual elements that a paragraph may occur. Such elements would also need to be added to the parameter entity %block-display.class; and to some individual element parameter entities.
