 * A declarative DOM directive for binding input, select, and textarea element values to a view model.

 * Syntax: `bind_value="namespace.propertyName"`
 *
 * Extends `BindTextDirective`. The crucial feature of `BindValueDirective` is its DOM write guard:
 * it compares the current element value with the incoming value and only writes to the DOM
 * when they differ. This prevents the browser from resetting the text cursor/selection position
 * when typing in an active text field.
 *
 * @example
 * ```html
 * <input
 *   type="text"
 *   bind_value="user.firstName"
 *   on-input="ui_edit_name:$value"
 * />
 * ```
