46--  A variable is considered a connectable element.
47--
48--  Variables are elements for passing data between actions indirectly. A
49--  local variable stores values shared by the actions within a structured
50--  activity group but not accessible outside it. The output of an action may
51--  be written to a variable and read for the input to a subsequent action,
52--  which is effectively an indirect data flow path. Because there is no
53--  predefined relationship between actions that read and write variables,
54--  these actions must be sequenced by control flows to prevent race
55--  conditions that may occur between actions that read or write the same
56--  variable.
