Re:  List type
Hi Graydon

Thanks for taking a look.

Your idea was my starting point too, but the trouble with
ancestor::list[not(descendant::steps)] is that if I'm the context node (a
list) I may have a steps *descendant* (which will thus also be a descendant
of all of my ancestors), but this descendant should not influence my
formatting. Steps only matter if they are my ancestors.

So I switched from this approach to trying to manipulate a sequence, but ran
out of ingenuity pretty quickly.

cheers
T

So if I'm standing on an li --

<xsl:template match="li">
    <xsl:choose>
        <!-- my parent list is a steps list -->
        <xsl:when test="parent::steps">
            <xsl:attribute name="list-type" select='decimal'/>
        </xsl:when>
        <xsl:when test="count(ancestor::list[not(descendant::steps)])
        mod 2 eq 0>
         <xsl:attribute name="list-type" select='alpha'/>
        </xsl:when>
        <xsl:when test="count(ancestor::list[not(descendant::steps)])
        mod 2 eq 1>
         <xsl:attribute name="list-type" select='decimal'/>
        </xsl:when>
    </xsl:choose>
<!-- other stuff -->
</xsl:template>

(I don't think I've managed to retain the correct style names for the list
types, so this won't be exactly right.)
