// Parameters scoped to allow for separating parameters from multiple models or
// model stages in a compiled pipeline. It's possible to have multiple files
// provide content for a single scope but not to have a single file provide
// content for multiple scopes. Since parameter keys only need to be unique
// within a scope this test could use the same name for both scopes if needed.
