This selection of a subset of the nodes can be a further specification of the subset selected by label=... e.g. S1=0.15 nodes=marked, which leaves the unmarked nodes unaltered and dc1=100 label=drain nodes=unmarked or dc1=100 nodes=unmarked label=drain which only effects unmarked nodes labelled drain.
