f175fae looks fine to me vs. the current spec.

I'd rather not refer to array entries by a property of their value (resource Type). I've filed opencontainers/runtime-spec#583, and if/when that lands referencing a particular entry by the resource will be more justified. If the runtime-spec PR is rejected, I can file a follow-up PR here so we report errors by index. Either way, I'm fine with this PR landing as it stands now, since checking with some ambiguity around the error message is better than no checking at all ;).
