Subject: Re: [docbook] epub3 cover bug?


That's a bug. The imageobject generates a table to manage a viewport, but that generated table does not get processed as a node set (as it should) to fix up its attributes for epub3.Â

The epub3 stylesheet takes:

       <cover>
            <mediaobject role="cover">
                <imageobject>
                    <imagedata width="554px" format="PNG" 
				fileref="images/TitlePage.png"/>
                </imageobject>
            </mediaobject>
        </cover>

and produces cover.xhtml:

<?xml version="1.0" encoding="utf-8" standalone="no"?>
<html xmlns="http://www.w3.org/1999/xhtml">
 <head>
  <title>Cover</title>
  <style type="text/css"> img { max-width: 100%; }</style>
 </head>
 <body>
  <div id="cover-image">
   <table border="0" style="cellpadding: 0; cellspacing: 0;" width="554">
    <tr>
     <td>
      <img src="" width="554"/>
     </td>
    </tr>
   </table>
  </div>
 </body>
</html>

But epubcheck3 isn't happy, because border="0" should be border="", and
<table> should have no width attribute.

Bug?  Or user error?
