Yes and it works when i use Saxon 9.5 whatever against the XML snippet that
I posted.

Unfortunately for me that is not how the XML manifests, rather it is the
product of some intermediate step and pipelined through a variable.

i.e the XML you saw is actually the content of a variable (call it $line)
which is the subject of an apply-templates as in <xsl:apply-templates
select="$line"/> where $line contains the posted XML.

Now that shouldn't make a difference but duplicates aren't being eliminated
in this scenario.

So the plot thickens.
