Which XSLT 2 processor do you use, any access to a proprietary "serialize"
function? Otherwise I guess you will need to write a function computing some
fingerprint, I think Dimitre has posted solutions on that in the past here.

Write a function that pushes each element through a mode that strips that
attribute, then let it serialize the result or compute a fingerprint, then use
that fingerprint or serialization in group-adjacent or group-by of
for-each-group, pushing the context node (i.e. first item in a group) through
the identity transformation with the collected

 B B B B B B B B B B B B B B B B B B B B B  <xsl:with-param name="refs"
tunnel="yes"
select="current-group()//terefs/teref"/>

as a tunnel parameter:


 B  <xsl:template match="mac">
 B B B B B  <xsl:copy>
 B B B B B B B B B  <xsl:apply-templates select="@*"/>
 B B B B B B B B B  <xsl:for-each-group select="*"
group-adjacent="mf:finger-print(.)">
 B B B B B B B B B B B B B  <xsl:copy>
 B B B B B B B B B B B B B B B B B  <xsl:apply-templates>
 B B B B B B B B B B B B B B B B B B B B B  <xsl:with-param name="refs"
tunnel="yes"
select="current-group()//terefs/teref"/>
 B B B B B B B B B B B B B B B B B  </xsl:apply-templates>
 B B B B B B B B B B B B B  </xsl:copy>
 B B B B B B B B B  </xsl:for-each-group>
 B B B B B  </xsl:copy>
 B  </xsl:template>


and insert it in

 B  <xsl:template match="teref">
 B B B B B  <xsl:param name="refs" tunnel="yes"/>
 B B B B B  <xsl:sequence select="$refs"/>
 B  </xsl:template>
