I think someone might confuse this for dead code and remove it. It might help to use natural language, e.g. `// `issuers` is in the form `[{origin: "http://foo.org/", permissions: ["issue"]}];`.

Perhaps even better (since that could get out of date) is to put a comment up near the `bpcModel.summarizeForUser` saying `// `issuers` is an array with information about the permissions a user has granted to various issuers, see [insert filename here] for details`
