When purchasing a deed for a court, three resources must be expended. Must the three consist of one of each resource listed?

When developing properties from deeds, must the mix of resources tokens follow the same rules as when completely developing a property? That is, must all the resource tokens match one of the card's suits, and must at least one of each suit be included?

Note that the Court's have a special rule, in that they count nothing for resource production [rolls of the die] but count 10 toward your total in the column [for scoring].

When developing from a deed to a property the resource token's must still match the card's suit but you need not have both included anymore as that requirement was met when playing it as a deed.
