can't add stylesheet link in document

I can’t add the stylesheet link in document, pls. help.

<?xml version="1.0" encoding="iso-8859-1"?>

<?xml-stylesheet type="text/xsl" href="test.xslt"?>

Thanks

Please elaborate on your process that you are trying to achieve?? what is the flow you have inplace??Also at what step it is failing??

Is your ISDocument/schema has the placeholder for the stylesheet link?
