and "\'" would produce ' instead of \' that it produces on conforming systems?

I can't see why you can't use variables, from perl I'd expect that
that you could assign strings to a variable in _perl_ syntax
with perl quoting, and then reference that variable by $x in a xpath
expression.

This would correspond using xsl syntax to assign variables that you
could reference in an xpath expression used in xsl.

Note xpath itself only has a syntax for referring to variables, not for
assigning them.
