deprecated and should not be used in any newly-written DocBook files. Use
#{mediaobject} instead.

We don't really ever want to embed external SVGs, because there's
no guarantee they exist at build time. But Yelp 2.30 launches an
external viewer when it encounters an <object> tag, so this is
the only option. When this was added, gnome-doc-utils and Yelp 2
are in maintenance (and hacks) mode. This works for some Ubuntu
docs that need SVG.

this template only chooses the first suitable #{imageobject} element. Support
for #{videobject} and #{audioobject} should be added in future versions, as well
as a text-only mode.
