inlinemediaobject — An inline media object (video, audio, image, and so on)
inlinemediaobject ::= (objectinfo?, (videoobject|audioobject|imageobject|imageobjectco|textobject)+)
               InlineMediaObject contains a set of alternative
               “graphical objects.” In DocBook V3.1, three types of
               external graphical objects are defined: VideoObjects,
               AudioObjects, and ImageObjects. Additional
               textual descriptions may be provided with TextObjects.
               
            
Formatted inline.
                  The primary purpose of the InlineMediaObject is to provide
                  a wrapper around a set of alternative presentations of the same
                  information.
                  
               
                  If possible, the processing system should use the content of the
                  first object within the InlineMediaObject.  If the first
                  object cannot be used, the remaining objects should be
                  considered in the order that they occur.  A processor should use
                  the first object that it can, although it is free to choose any
                  of the remaining objects if the primary one cannot be used.
                  
               
                  Under no circumstances should more than one object in an
                  InlineMediaObject be used or presented at the same time.
                  
               
                  For example, an InlineMediaObject might contain a high
                  resolution image, a low resolution image, and
                  a text description. For print publishing, the high resolution image is used;
                  for online systems, either the high or low resolution image is used,
                  possibly including the text description as an online alternative.
                  In a text-only environment, the text description is used.

The following elements occur in inlinemediaobject:
                  audioobject, imageobject, imageobjectco, objectinfo, textobject, videoobject.
               
alt, audioobject, caption, graphic, imageobject, inlinegraphic, mediaobject, textobject, videoobject.
               
            
               In the following example, the InlineEquation uses
               InlineMediaObject to provide to alternate renderings
               for the equation. One is a graphic, the other is a text representation.
               
            
For display purposes, both in print and in the online presentation, the graphic is selected. If you were generating content for some other medium, a text only browser or a cell phone, for example, only the text representation might be selected.
