#7 is a legal character in XML 1.1, but not in XML 1.0. You can output it in
Saxon if you enable XML 1.1 by (a) using the -xmlversion:1.1 switch on the
command line or the equivalent in the Java API.

Alternatively, you can output characters that are disallowed in XML by using
the processing instruction

<xsl:processing-instruction name="hex.ascii" select="'07'"/>

together with <xsl:output saxon:recognize-binary="yes"/>

#7 is actually the BEL character - in my youth, if you sent it to a
teletype, it rang the bell (a real bell, not just an electronic beep). Using
it to mean "indent to here" seems to be code abuse.
