RE: [xsl] Xref numbering test

Thanks for all the suggestions, here is how I made it work. I don't know
if this is the best way but it works for my application.

    <xsl:when test="@xidtype='step'">
        <fo:basic-link background-color="lightblue"
internal-destination="{@idref}">
            <xsl:for-each select="key('ids',@xrefid)">
            <xsl:if test="substring(@id, 1, 6)='step1-'">
                <xsl:text>Step </xsl:text>
                    <xsl:number count="step1" from="mainfunc|closeup"
level="multiple" format="1"/>
            </xsl:if>
            <xsl:if test="substring(@id, 1, 6)='step2-'">
                <xsl:text>Step </xsl:text>
                    <xsl:number count="step1|step2"
from="mainfunc|closeup" level="multiple" format="1.1.1.1"/>
            </xsl:if>
            <xsl:if test="substring(@id, 1, 6)='step3-'">
                <xsl:text>Step </xsl:text>
                    <xsl:number count="step1|step2|step3"
from="mainfunc|closeup" level="multiple" format="1.1.1.1"/>
            </xsl:if>
            <xsl:if test="substring(@id, 1, 6)='step4-'">
                <xsl:text>Step </xsl:text>
                    <xsl:number count="step1|step2|step3|step4"
from="mainfunc|closeup" level="multiple" format="1.1.1.1"/>
            </xsl:if>
            <xsl:if test="substring(@id, 1, 6)='step5-'">
                <xsl:text>Step </xsl:text>
                    <xsl:number count="step1|step2|step3|step4|step5"
from="mainfunc|closeup" level="multiple" format="1.1.1.1"/>
            </xsl:if>
            </xsl:for-each>
        </fo:basic-link>
    </xsl:when>

True.  But there's no need to spell *everything* out is there?  Surely a
point in the right direction is better than a 'cut and paste' in the
long run...

I recognise the element names and have worked on this kind of dtd for a
few years, so (I think) I know the requirements even if norma didn't
quite spell them out :)

I still stand by using variables in this situation, they really help
maintaining and debugging the process involved.
