DocBook to HTML - Images and Media
Handle DocBook media elements.
@revision[version=3.8 date=2012-11-13 status=final]
This stylesheet contains templates for handling DocBook `mediaobject` and
`inlinemediaobject` elements, as well as the various `object` and `data`
elements found in these elements. This stylesheet also handles the deprecated
DocBook 4 `graphic` and `inlinegraphic` elements.

This template creates an `audio` element in the HTML output. This template

Output an HTML `img` element for a `imagedata` element.
@revision[version=3.10 date=2013-08-11 status=final]
[xsl:params]
$node: 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.

db2html.mediaobject
Outputs HTML for a `mediaobject` element.
@revision[version=3.10 date=2013-08-11 status=final]
[xsl:params]
$node: The `mediaobject` element.
This template processes a `mediaobject` element and outputs the appropriate
HTML. DocBook allows multiple objects to be listed in a `mediaobject` element.
Processing tools are expected to choose the earliest suitable object. This
template will select the first audio, image, or video object it can handle,
filtering out images in non-web formats, and taking conditional processing
into consideration. If no suitable non-text objects are found, this template
calls {db2html.mediaobject.fallback}.
This template also detects MathML embedded in a DocBook 5 `imagedata` element
with the `format` attribute `"mathml"`, and passes it to the templates in
{db2html-math}.
