Please add a method to to specify xml-stylesheet processing instruction

Question

Documents which require referencing an external xsl require a processing instruction as below to be inserted below the prolog

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

Please allow a way to specify this node and have it included to calls to `emit'. Ideally a way to specify arbitrary processing instructions and prepend them before the root node.
