Elements that may be used at the same structural level as a paragraph, for example, inside a section.
DTD Design Note: There is a major overlap between this Parameter Entity and that for the elements that may occur inside a paragraph (%inside-para;). Inline elements appear only inside a paragraph, while block elements such as quotes and lists may appear either within a paragraph or at the same level as a paragraph. This serves a requirement in a repository DTD, since some incoming material will have restricted such elements to only inside a paragraph, some incoming material will have restricted them to only outside a paragraph, and some may allow them in both places. Thus, the DTD must allow for them to be in either or both locations.
