  That works. I tried 
  and also

  Both didn't work.

inside the [] the current bode is the answer element (that's why @ref
finds the ref attribute of answer) but that means that self::node() is
also the answer element so self::node()/@id and @id are both
syntactically correct but are comparing the ref attribute with an id
attribute on the same element the id attribute isn't there but that's OK
it will compare as "" as usual in xpath.
current() is the node current at the _start_ of the xpath so that gets
you back to the question node.
