UMLR — Minor error in ptc-13-09-05

  • Key: UMLR-360
  • Legacy Issue Number: 19637
  • Status: open  
  • Source: Model Driven Solutions ( Steve Cook)
  • Summary:

    In ptc-13-09-05.pdf on page 9 it says:

    Where items need to be grouped they are enclosed in simple parenthesis; for example:

    (<item-1> | <item-2>) *

    signifies a sequence of one zero or more items, each of which is <item-1> or <item-2>.

    I think the word one must be replaces by zero because on page 28 it says:

    If the lower bound is equal to the upper bound, then an alternate notation is to use a string containing just the upper bound. For example, “1” is semantically equivalent to “1..1” multiplicity. A multiplicity with zero as the lower bound and an unspecified upper bound may use the alternative notation containing a single star “” instead of “0..” multiplicity.
