Thank you Michael !
That option makes poly.xml a polyglot (cheating) quine (program is its own output)
https://en.wikipedia.org/wiki/Quine_(computing)#.22Cheating.22_quines
as well (after removing the newline at file end):
$ java net.sf.saxon.Query -q:poly.xml \!omit-xml-declaration=yes > xq
$ java net.sf.saxon.Transform -xsl:poly.xml -s:dummy.xml \!omit-xml-declaration=yes > xsl
$ diff xq xsl
$ diff xq poly.xml
