// The `listentry` template is designed to let you perform list check operations
// with the [list](https://istio.io/docs/reference/config/adapters/list.html) adapter.
//
// The `listentry` template is used to verify the presence/absence of a string
// within a list.
// 
// When writing the configuration, the value for the fields associated with this template can either be a
// literal or an [expression](https://istio.io/docs/reference/config/mixer/expression-language.html). Please note that if the datatype of a field is not istio.mixer.adapter.model.v1beta1.Value,
// then the expression's [inferred type](https://istio.io/docs/reference/config/mixer/expression-language.html#type-checking) must match the datatype of the field.
// 
// Example config:
// ```
// apiVersion: "config.istio.io/v1alpha2"
// kind: listentry
// metadata:
//   name: appversion
//   namespace: istio-system
// spec:
//   value: source.labels["version"]
// ```
