# to stub an API call using this model. That way if the models ever
# change we have a mechanism to ensure that the existing models continue
# to work with botocore. The test should not change (with the exception
# of potential changes to the ClientHTTPStubber), and the files in
# tests/functional/models should not change!

# if we end up adding a new data file that's needed to create clients.
