The SRG (i) and the signature (ii) are the same as in 7.3.4. The NAG (iii)
shows the time-linear activation order of the SRG. The surface realization (iv)
shows the use of the traversal order for production in English.
A numbered arcs graph may be defined for an SRG, a signature, or a proplet
graph. Consider the NAG based on the proplet graph 7.3.4:
