textobject — A wrapper for a text description of an object and its associated meta-information
TextObject is a wrapper containing a textual description of a media object, and its associated meta-information.
TextObjects are only allowed in
MediaObjects as a fall-back option, they cannot be the primary content.
There are two different forms of
TextObject, and it is not unreasonable for a media object to contain both of them.
In the first form, the content of a
TextObject is simply a
Phrase. This form is a mechanism for providing a simple “alt text” for a media object. The phrase might be used, for example, as the value of the
ALT attribute on an HTML
IMG, with the primary content of the image coming from one of the other objects in the media object.
In the second form, the content of
TextObject is a longer, prose description. This form could be used when rendering to devices that are incapable of displaying any of the other alternatives.
May be formatted inline or as a displayed block, depending on context. It might not be rendered at all, depending on its placement within a
InlineMediaObject and the constraints on the publishing system. For a more detailed description of the semantics involved, see
