Umbraco Validation Context

Handles form validation in Umbraco's backoffice using the centralized UmbValidationContext system. You bind fields to JSON Path identifiers like `$.form.tab1.email`, trigger validation with `validate()`, and observe error counts reactively for tabs or entire forms. The examples show the common pattern: multi-tab workspace editors where you need error badges on tabs and validation messages next to inputs. It integrates with Umbraco's uui-form-validation-message components and supports both immediate feedback and submit-time validation. The source includes working dashboard examples if you need reference implementations for workspace contexts or complex multi-step forms.
