If you are using the -Fe compiler option to generate XML-style XFD files, the XSL directive allows you to include a stylesheet reference in the XML header.
$XFD XSL=stylesheet
or
*(( XFD XSL="stylesheet" ))
where stylesheet is an alphanumeric literal indicating the appropriate stylesheet. The compiler includes the following line in all generated XML-style 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"?>
