The imagedata or other graphic element.
This template creates an img element in the HTML output. This template is called not only for imagedata elements, but also for graphic and inlinegraphic elements. Note that graphic and inlinegraphic are deprecated and should not be used in any newly-written DocBook files. Use mediaobject instead.
This template looks for a textobject with a phrase child in an ancestor mediaobject or inlinemediaobject element. It uses the first available, taking conditional processing into consideration.
