  17. My original posting was not terribly explicit.  My interpretation of the
  18. wording in Table 7 is that an assignment x=y cannot share the string data
  19. of y.  My interpretation of Table 3 for the copy constructor is the same:
  20. string x(y) cannot sahre y's data.  I conclude, therefore, that a counted
  21. pointer representation is allowed in theory but 'prevented in practice'.
