epub: how to set linear = 0

Kindle requires that an epub file have

        <itemref idref="cover" linear="no"/> in order for the Kindle
file not to show the cover twice.

In my output in content.opf  I see the lines

<spine toc="ncxtoc">
   <itemref idref="cover" linear="yes"/>

In the epub/docbook.xsl file I see a parameter at the top which says:

  <xsl:param name="epub.cover.filename"
select="concat($epub.oebps.dir, 'cover', $html.ext)"/>
  <xsl:param name="epub.cover.id" select="'cover'"/>
  <xsl:param name="epub.cover.html" select="'cover.html'" />
  <xsl:param name="epub.cover.image.id" select="'cover-image'"/>
  <xsl:param name="epub.cover.linear" select="0" />

I would assume that for epub.cover.linear, if the value is 0, then
linear is supposed to be "no". But by default it seems to show a yes
value in my output. If I change the parameter to   <xsl:param
name="epub.cover.linear" select="1" /> I get the exact same result.

Is this a bug?
