Attributes
Description
A TextObject
is a wrapper containing a textual description of a media object, and its associated meta-information. TextObject
s are only allowed in MediaObject
s 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.
Processing expectations
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 MediaObject
or InlineMediaObject
and the constraints on the publishing system. For a more detailed description of the semantics involved, see MediaObject
.
