<graphic>
Graphic
Description of and pointer to an external file containing a still image.
Remarks
The external file associated with a <graphic> holds a picture, illustration, etc., and is usually some form of
binary object. The “content” of the <graphic> element (if any) is not the object itself, but
merely information about the object. The external file that contains the object is
named by the @xlink:href attribute.
Related Essay: For a discussion on the use of <graphic>, see Figures and Graphics.
Position: Although the @position attribute of this element may be used to indicate whether this element must be anchored at its exact
location within the text or it may float, it is good practice to anchor graphics. All the graphics inside figures, tables, etc., should be anchored as well, although the outer structure (figure, boxed text) may be allowed to float.
Usage: Display component elements, such as <caption>, should always be used at the highest possible level; in other words, if a <graphic> element is inside a <fig> element, the <caption>, <long-desc>, etc., should be part of the <fig>, not part of the <graphic> element. Use a <caption> element (and similar display component elements) on a <graphic> only when the graphic object is not enclosed in any other structure or when a figure contains multiple graphic objects, each of which must have its own <caption>. For similar reasons, the @position attribute should be set to “anchor” for a <graphic> element contained inside a larger display container such as a <fig>.
