Not sure about CLI behavior. But, YDK is based on YANG model which only allows values which fit a pattern. This info is available in YDK documentation for this class: http://ydk.cisco.com/py/docs/gen_doc_b34e5d6cd3d0eea7a1ccb30a13b2caa9ee8f64c4.html#ydk.models.cisco_ios_xr.Cisco_IOS_XR_policy_repository_cfg.RoutingPolicy.RoutePolicies.RoutePolicy

Thank you abhirame, and I have already found the definition of this pattern in Cisco-IOS-XR-policy-repository-cfg.yang and Cisco-IOS-XR-types.yang , it looks like a Yang definition error.
