The XSL directive allows you to include a stylesheet reference in the XML header of your XFDs when they are created.
$XFD XSL=stylesheet
where stylesheet is an alphanumeric literal indicating the appropriate stylesheet. The compiler includes the following line in all generated XFD files:
<?xml-stylesheet type="text/xsl" href="stylesheet"?>
For example:
$XFD XSL="myxsl.xsl"
generates this line:
<?xml-stylesheet type="text/xsl" href="myxsl.xsl"?>
