<graphic> Graphic
Description of and pointer to an external file containing a still image.
Usage/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 and a pointer to an external file. The external
file that contains the object is
named by the @xlink:href attribute.
Graphic versus Figure
It is considered Best Practice to tag unlabeled graphics (no label such as “Figure
4.”) as <graphic> elements, rather than as <fig> elements. A common test to determine whether an object is a <fig> versus a <graphic> is to ask, “If there were a List of Figures for this document, should this object appear in that list?”
Graphic versus Media
Although this Tag Set cannot enforce it, the element <graphic> should be limited to still images. The element <media> should be reserved for objects that involve video, audio, moving images, time-dependent
graphical types, and other non-XML data types. Such external objects should take a
@mimetype, when possible.
Put Display Components at Highest Level Possible
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 is not enclosed in any other structure or when a figure contains
multiple graphics, each of which must have its own <caption>.
Accessibility
For Best Practice, a <graphic> that is not inside a <fig> or <table-wrap> should contain both <alt-text> and <long-desc>, which are especially important to enable access for visually impaired users. For
graphics inside another element (such as a <fig>), the containing element typically holds the accessibility elements, although in
rare cases the accessibility elements may need to be used in both places. For usage
notes and recommendations, see Accessibility.
Anchoring 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 all loose
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.
