UML14 — Section 8.3.3 Realization

The text states, "A component realization is notated in the same way as the realization dependency, i.e. as a general dashed line with an open arrow-head." What is an open arrowhead. Compare and contrast that with the "stick arrowhead" described in the Presentation Options section of Class in Composite Structures (page 156). Stick arrowhead can be found 6 times in the spec, while open arrowhead can be found 4 times. They all appear to refer to the same notation. I recommend that you chose one term.
