<media> Media Object
Description of and pointer to an external file that holds a media object (for example, an animation, an audio file, or a movie).
The @position attribute may be used to indicate whether this element must be anchored at its exact location within the text or whether it may float, but Best Practice is to anchor graphics and media objects. The few media objects that occur within the narrative text should be anchored in place, and all the media objects inside figures, tables, etc., should be anchored as well, although the outer structure (figure, boxed text) may be allowed to float.
Best Practice Usage
Display component elements, such as <caption>, should always be used at the highest possible level; in other words, if a <media> element is inside a <fig>, the <caption>, <long-desc>, etc., should be part of the <fig>, not part of the <media>. Use a <caption> element on a <media> only when the media object is not enclosed in any other structure or when a figure contains multiple media objects, each of which must have its own <caption>. For similar reasons, the @position attribute should be set to “anchor” for a <media> element that is inside a larger display container such as a <fig>.
When Content is a Form
The @is-form attribute can be used to indicate that the media object contains a form. What constitutes a “form” is not defined by NISO STS.
