Subject: accessibility and xhtml/html5 xsl
Hi,
I am working on an epub(3) accessibility project and therefore I have
had a look at the html5 generated by the latest docbook xslt.
Looking at the html5 generated by the epub3 xsl, I see some tagging
patterns that are not quite accessible, like the use of <span
class="italic"> or of structure in the titlepages like:
<body>
<div class="sect1" title="foo" epub:type="subchapter">
<div class="titlepage">
<div>
<div>
<h2 class="title" style="clear: both" id="idp17104">
Both of these examples are probably going to confuse screen readers
and other assistive technologies.
If I remember correctly, the h2 used for section1 titles (therefore
missing the h1 level) derives from how the xhtml stylesheets have been
built years ago, so I guess it is not trivial to correct this
behavior. And I think also the tables will need some reworking (like
the use of scope and headers attributes for td/th).
My question is: what is the best approach to have a better accessible
and semantically structured html5 output (particularly for epub3
output)?
The two approach that come to my mind are:
* yet another customization layer;
* a postprocessing phase done externally of the docbook toolchain by
means of a python script or the like.
Opinions?
Thanks,
