### 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)

// isEmpty returns true if Tags field is null
func (a And) isEmpty() bool {
	return len(a.Tags) == 0 && !a.Prefix.set &&
		a.ObjectSizeGreaterThan == 0 && a.ObjectSizeLessThan == 0
}

// Validate - validates the And field
func (a And) Validate() error {
	// > This is used in a Lifecycle Rule Filter to apply a logical AND to two or more predicates.
