Subject: Re: [docbook-apps] why do user templates generate empty xmlns attributes?
I am happy to report that your explanation makes perfect sense. And
including a xhmtl namespace declaration (in addition to the Transform
namespace) does the job:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns="http://www.w3.org/1999/xhtml";
version="1.0">
It leaves me wondering why the epub transform wouldn't already include
this information already.
By the way, I figured out the problem with the processing which wasn't
processed. Apparently, it looks for the <?dbhtml-include
href="fragment1.html"?> file inside the directory of the default
docbook stylesheet, NOT the directory of the source XML. (This also
seems strange and a little unwieldy for me, but maybe the intent was
to use this functionality not for individual projects. Thanks again.
