Thanks. That worked (explicitly loading closure-common first), however I'm
experiencing trouble in running the first example of the QuickStart guide:

(cxml:with-xml-output (cxml:make-octet-stream-sink test-sequence-file
:indentation 2 :canonical nil)
    (cxml:with-element "foo"
      (cxml:attribute "xyz" "abc")
      (cxml:with-element "bar"
        (cxml:attribute "blub" "bla"))
      (cxml:text "Hi there.")))

Produces an error: "value 60 is not of the expected type CHARACTER."

I suspect this might be related to character encoding, as the backtrace
(below) mentions two encodings, UTF-8 and ISO-8859-1.

 14: (GENERATE-TEST-SEQUENCE "banking.xml")
 15: (CCL::CALL-CHECK-REGS GENERATE-TEST-SEQUENCE "banking.xml")


The entire function is:

(defun generate-test-sequence (file-name)
  (with-open-file (test-sequence-file file-name
                      :direction :output
                      :if-exists :supersede)

    (cxml:with-xml-output (cxml:make-octet-stream-sink test-sequence-file
:indentation 2 :canonical nil)
      (cxml:with-element "foo"
    (cxml:attribute "xyz" "abc")
    (cxml:with-element "bar"
      (cxml:attribute "blub" "bla"))
    (cxml:text "Hi there.")))))

Cheers,
