
  <use><qd>action</></>

  becomes something like;

  [TOKEN name="use"]
  [TOKEN name="qd"]
  [TOKEN value="action"]
  [ENDT]
  [ENDT]

then process line by line? I can feel a stack is going to be needed. I think I need to have a play with getting results from the expected token format (written by hand) so I can be sure how the system will work post-tokenisation. (then write the tokeniser)
