Unless the sink is in canonical mode (and canonical isn't the default
anymore in current cxml), newline characters in text are written
literally, so just write text including a newline.  Example:

CL-USER> (cxml:with-xml-output (cxml:make-string-sink)
           (cxml:with-element "test"
             (cxml:text (format nil "foo~%bar"))))
"<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<test>foo
bar</test>"


That's for manual breaks.  If you were hoping for automatic indentation,
there's the :INDENTATION keyword argument:

CL-USER> (cxml:with-xml-output (cxml:make-string-sink :indentation 2)
           (cxml:with-element "outer"
             (cxml:with-element "inner"
               (cxml:text (format nil "foo~%bar")))))
"<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<outer>
  <inner>
    foo bar</inner>
</outer>"

The indentation support isn't very good though.  I use it only for
debugging purposes.  Also note that it reindents texts, removing the
explicit newline.
