I'm working on an XSL 1.0 stylesheet that processes a DocBook Website
autolayout file, transforming its Website pages into DocBook 5 articles.
My stylesheet imports Norm's db4-upgrade.xsl, which does most of the
work. My output is valid, and looks fine except for one nagging detail:
some elements are transformed with 'version="5.0" attributes.
Sample output:
=====================
<article xmlns="http://docbook.org/ns/docbook";
xmlns:xi="http://www.w3.org/2001/XInclude";
xmlns:html="http://www.w3.org/1999/xhtml";
xmlns:m="http://www.w3.org/1998/Math/MathML";
xmlns:svg="http://www.w3.org/2000/svg";
xmlns:xlink="http://www.w3.org/1999/xlink"; version="5.0" xml:id="upreview">
<?dbhtml filename="upreview.html" dir="arts"?>
<title>Up and other Pixar reviews</title>
<para version="5.0">From
<citetitle>Pixar Gone Too Far This Time</link></citetitle>: </para>
<blockquote version="5.0">
<para><quote>If the Pixar sensibility seemed strangely locked in to
a mid-20th century mindset, well, they made it clear they intended to
inherit the Disney mantle, didn’t they?</quote></para></blockquote>
...
</article>
=====================
Notice that all the children of <article> (except for <title>, which my
stylesheet extracts out of context) have the version attribute, while
their children do not. I'd like the version attribute to be suppressed
on all elements (except the root article, of course). Any ideas? Here's
the entire customization:
