### Validations

Both the `IstioOperatorSpec` and Helm APIs are validated. The `IstioOperatorSpec` API is validated through a
table of validation rules in
[pkg/validate/validate.go](pkg/validate/validate.go). These rules
refer to the Go struct path schema and hence have names with a capitalized first letter.
The Helm values.yaml API is validated in
[validate_values.go](pkg/validate/validate_values.go)
