DOCBOOK-APPS: ALT tags and the <textobject>

[Dennis Grace <dgrace at us dot ibm dot com>]

To ensure the accessibility of my HTML, I want to provide ALT tags for my
imageobjects. I've looked through the archives, and the advice I keep
seeing is "use the textobject" tag. Unfortunately, when I use something
like this:

<mediaobject>
      <imageobject>
            <imagedata fileref= "picture.png">
      </imageobject>
      <textobject>
            <para>Description of picture<para>
      </textobject>
</mediaobject>

the resulting HTML page contains the image, followed by a link labeled
'[D]', which connects to a separate HTML page containing the phrase
"Description of the picture."

I'm processing XSL 1.55.0 with the latest xsltproc.

Am I missing something obvious, or do I need to start writing a new
customization to turn the <textobject> into an actual ALT tag?
