struct.

Other per-component mappings to Helm values.yaml are expressed in the
[ComponentMaps](https://github.com/istio/operator/blob/e9097258cb4fbe59648e7da663cdad6f16927b8f/pkg/translate/translate.go#L83)
struct.

### 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

Navbar\n// Navbar brand\n// Navbar nav\n// Navbar text\n// Navbar divider\n// Responsive navbar\n// Navbar position\n// Navbar themes\n\n\n// Navbar\n//\n// Provide a static navbar from which we expand to create full-width, fixed, and\n// other navbar variations.\n\n.navbar {\n  position: relative;\n  display: flex;\n  flex-wrap: wrap; // allow us to do the line break for collapsing content\n  align-items: center;\n  justify-content: space-between; // space out brand from logo\n  padding: $navbar-padding-y...

### Other (Cleanup or Flake)

	if t, ok := config.Tiers[tierName]; ok {
		return t.Type, true
	}
	return madmin.Unsupported, false
}

// Add adds tier to config if it passes all validations.
func (config *TierConfigMgr) Add(ctx context.Context, tier madmin.TierConfig, ignoreInUse bool) error {
	config.Lock()
	defer config.Unlock()

	// check if tier name is in all caps
	tierName := tier.Name

You can use all the same validation features and tools you use for Pydantic models, like different data types and additional validations with `Field()`.

Define extra validations for data types using the "default" value of model attributes. This improves editor support, and it was not available in Pydantic before.
