Well set_stylesheet_uri doesn't return the object (at the moment), plus
you'd need to remove your outer quotes...

However I suggest for XSLT (and perhaps anything that takes a stylesheet),
to define it outside of the Machine:

  my $xslt = XML::Filter::XSLT-> new();

  my $machine = Pipeline(
	$xslt =>  XML::Filter::PDF => \*STDOUT
  );

  $xslt-> set_stylesheet_uri('my_pdflib.xsl');

  $machine-> parse_uri('foo.xml');

Then you're free to reuse the machine, and also to change your XSLT at any
time.
