It's not only possible, but quite normal, that an action loads more than one data model. Using the singular, suggesting that it (necessarily or typically) loads only one model, is confusing. You may want to consider these alternatives: - "The action loads zero or more data models" - "The action optionally loads one or more data models" but I guess "some models" is clear enough.
