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
