+    Documentation test: This test documents the key use case for skip_validation.
+
+    The skip_validation flag is particularly important for On-Demand Feature Views (ODFVs)
+    that use feature transformations. During the apply() process, ODFVs call infer_features()
+    which internally uses _construct_random_input() to validate the transformation.
+
+    Sometimes this validation can be overly strict or fail for complex transformations.
+    In such cases, users can use skip_validation=True to bypass this check.
+
+    Example use case from the issue:
+    - User has an ODFV with a complex transformation
+    - The _construct_random_input validation fails or is too restrictive
+    - User can now call: fs.apply([odfv], skip_validation=True)
+    - The ODFV is registered without going through the validation
+
+    Note: Users should be encouraged to report such cases on GitHub so the Feast team
+    can improve the validation system.
