 A `check` block can optionally contain a nested (a.k.a. scoped) data source. This `data` block behaves like an external [data source](/terraform/language/data-sources), except you can not reference it outside its enclosing `check` block. Additionally, if a scoped data source's provider raises any errors, they are masked as warnings and do not prevent Terraform from continuing operation execution.
