Named Special (Subject) Content

Word or phrase whose content/subject matter has distinct semantics or content-related significance.


In print or display, such semantic content is likely to be treated differently, for example, given a stand-out typographic style such as italics or background shading.


alt Alternative Text
content-type Type of Content
id Document Internal Identifier
rid Reference to an Identifier
specific-use Specific Use
xlink:actuate Actuating the Link
xlink:href Href (Linking Mechanism)
xlink:role Role of the Link
xlink:show Showing the Link
xlink:title Title of the Link
xlink:type Type of Link
xmlns:xlink XLink Namespace Declaration

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".

Best Practice: Similarly, if a word is in italics because it is a foreign phrase, one very typical way to tag it would be as:

...remarkable for his <named-content 
xml:lang="fr">joie de vivre</named-content>
and lively expression.

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.
