<!--
see https://en.wikipedia.org/wiki/ANSI_escape_code#3/4_bith;
note that we need to retain XML 1.0 (as opposed to 1.1, which in turn
is not supported in libxml) compatibility in this very template, meaning
we cannot output a superset of what's expressible in the template itself
(escaped or not), hence we are forced to work that around for \x1b (ESC,
unavoidable for ANSI colorized output) character with encoding it in some
way (here using "\x1b" literal notation) and requiring a trivial
"xsltproc ... | sed 's/\\x1b/\x1b/'" postprocessing;
the above, however, only applies when used directly (which may be the
reason to pay attention to this comment to begin with), but fortunately
it is conveniently avoidable when XSLT triggered programatically (see
pcmk__acl_evaled_render), since libxslt allows for passing raw (further
unchecked) parameter strings, in which case the actual content of those
parameters is decoded on the fly, meaning that this file is still open
to compilation-free customizations if there's an irresistible need...
