[xsl] We need to kick someone out of the group

Hi all,

Sometimes I am baffled about how to approach something. Sometimes I'm baffled 
by why something doesn't work.    

Using XSLT 2.0, I have the input XML:

    <contrib-group>
        <contrib><name>Bob</name><xref rid="aff1"/></contrib>
        <contrib><name>Judy</name><xref rid="aff2"/></contrib>
    </contrib-group>
    <aff id="1"><label>1</label>Kingdom of Curds</aff>
    <aff id="2"><label>2</label>Land of Whey</aff>
    <contrib-group>
        <contrib><name>Jimmy</name><xref rid="aff3"/></contrib>
    </contrib-group> 
    <aff id="3"><label>2</label>Duchy of Lambic-Soaked Cheese Rind</aff>    

I'm trying to get:

    <contrib-group>
        <contrib><name>Bob</name><xref rid="aff1"/></contrib>
        <contrib><name>Judy</name><xref rid="aff2"/></contrib>
        <aff id="1">Kingdom of Curds</aff>
        <aff id="2">Land of Whey</aff>
    </contrib-group>
    <contrib-group>
        <contrib><name>Jimmy</name><xref rid="aff3"/></contrib>
        <aff id="3">Duchy of Lambic-Soaked Cheese Rind</aff>   
    </contrib-group>

That is, move the following <aff> elements into the <contrib-group> and remove 
the <label>. But what I get is

    <contrib-group>
        <contrib><name>Bob</name><xref rid="aff1"/></contrib>
        <contrib><name>Judy</name><xref rid="aff2"/></contrib>
        <aff id="1">Kingdom of Curds</aff>
        <aff id="2">Land of Whey</aff>
        <aff id="3">Duchy of Lambic-Soaked Cheese Rind</aff>   
    </contrib-group>
    <contrib-group>
        <contrib><name>Jimmy</name><xref rid="aff3"/></contrib>
        <aff id="3">Duchy of Lambic-Soaked Cheese Rind</aff>   
    </contrib-group> 
    
That is, the third <aff> is getting drawn into the first <contrib-group>. Even 
I could figure out that starting from the context node <contrib-group>, the 
following-sibling axis would draw in all three <aff> elements. But that's what 
grouping is for, so...

    <xsl:template match="contrib-group">
        <xsl:copy>
            <xsl:apply-templates/>
            <xsl:for-each-group select="following-sibling::aff" 
group-starting-with="contrib-group">
                <xsl:for-each select="current-group()">
                    <xsl:copy >
                        <xsl:attribute name="id"><xsl:value-of 
select="./@id"/></xsl:attribute>
                        <xsl:apply-templates/>
                    </xsl:copy>
                </xsl:for-each>
            </xsl:for-each-group>
        </xsl:copy>
    </xsl:template>
    
    <xsl:template match="aff"/>
    <xsl:template match="aff/label"/>

I've tried different grouping variations, like using @group-adjacent, but I get 
the same result. I have a feeling that the problem is in the <xsl:for-each 
select="current-group()">, but this template looks a lot like the sample code 
on various tutorials.

???

(I've gotten much help from this list, and I really need to take the time to 
get further in Ken's Udemy course! The next time I see any of you, I'll owe you 
a beer, a homebrew if I'm not flying. I've got a robust porter wet-hopped from 
the vines in my back yard and a Flemish sour with black currants.)

Thanks,
Charles
