Does this form of the test work for elements that only contain other
elements (i.e. no text nodes)? Example: <a href="..."><img ... /></a>

In on of my stylesheets I ended up with this code due to problems
associated with the mixed content model of "jump":

  <xsl:template match="jump">
    <xsl:choose>
      <xsl:when test="count(child::* | text()) = 0">
        <a href="{@href}"><xsl:value-of select="@href"/></a>
      </xsl:when>
      <xsl:otherwise>
        <a href="{@href}"><xsl:apply-templates/></a>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>


Ciao, Jürgen
