I think this is about as far as you can get with the 'plain XProc' approach. You can also imagine inserting a "<?xml-stylesheet?>foo" document into the original document and the using p:delete to remove the "foo" element, but that is just a variation on the same theme. The problem is that the content of p:inline must be a well-formed XML document, so you cannot specify a processing instruction without some kind of a dummy document element next.

What about using p:xslt (p:xquery?) to add the PI?
