I would use group-starting-with in a template matching the parent or
node e.g.


   <xsl:template match="*[contrib-group]">
        <xsl:copy>
            <xsl:for-each-group select="*"
group-starting-with="contrib-group">
                    <xsl:copy>
                        <xsl:apply-templates select="@*, node(),
tail(current-group())"/>
                    </xsl:copy>
            </xsl:for-each-group>
        </xsl:copy>
    </xsl:template>


    <xsl:template match="aff/label"/>


Assumes the identity template set up. tail(current-group()) is
subsequence(current-group(), 2) in XSLT 2.
