-  <pre>Lints a Cloud IAM policy object or its sub fields. Currently supports
-google.iam.v1.Binding.condition.
+  <pre>Lints, or validates, an IAM policy. Currently checks the
+google.iam.v1.Binding.condition field, which contains a condition
+expression for a role binding.
 
-Each lint operation consists of multiple lint validation units.
-Each unit inspects the input object in regard to a particular linting
-aspect and issues a google.iam.admin.v1.LintResult disclosing the
-result.
-
-The set of applicable validation units is determined by the Cloud IAM
-server and is not configurable.
-
-Regardless of any lint issues or their severities, successful calls to
-`lintPolicy` return an HTTP 200 OK status code.
+Successful calls to this method always return an HTTP `200 OK` status code,
+even if the linter detects an issue in the IAM policy.
