  attribute value change
The following seems to work:

declare namespace local = "http://example.com/functions";

declare function local:copy($element as element()) {
  element {node-name($element)}
    {$element/@*[not(name() eq 'id')], if (local-name($element) eq 'chap') then
	                                             (attribute id {
concat($element/preceding::bn, '_',            $element/@id) }) else
(),
     for $child in $element/node()
        return if ($child instance of element())
          then local:copy($child)
          else $child
    }
};

local:copy(doc('test.xml')/*)
