You're certainly right that, if the interface doesn't promise that each
property's value is presented at most once, its clients shouldn't assume
that. I'm glad Philip says that the extant delta producers do actually
follow this rule; it's nicely consistent with the restrictions on the order
in which producers can call the other editor functions. We made those
restrictions to make life easier for delta consumers; hopefully this
restriction will do the same.
