Named Special (Subject) Content

A word or phrase whose content/subject matter has special semantics or content-related significance. In print or display, such content is likely to be treated differently, for example, given a special typographic style such as italics or background shading.

Related Elements

The related <styled-content> element may, in some instances, produce the same look on print or display as some <named-content> elements. Both mark content that has a visual distinction; the difference between the two elements is intent. If it is known that this word is in italics because it is a genus or species name, those semantics should be preserved with a <named-content> element with a @content-type attribute of “genus-species” or equivalent. The <styled-content> element would merely tell you that it was always in green shaded background style="green-shading".

Being web-only or print-only is not a stylistic matter, but rather a particular use, which should be tagged with the @specific-use attribute on the appropriate element, perhaps even on a <named-content> or <styled-content> element.
