We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Allow creating attributes with values in one mutation
We need to change the signature of `productAttributeCreate` mutation to allow creating attribute values in the same mutation. This is required by the new UI for the product attributes dashboard.

--- END ISSUE ---

Below are some code segments, each from a relevant file. One or more of these files may contain bugs.
