           Summary: How to use @required on dependent elements with
                    no-Javascript clients
           Product: HTML WG

When building forms with required dependent elements, there is no way to modify
@required on dependent elements without Javascript.

Example:

<form>
<label><input type="checkbox" />Use shipping address for billing</label>
<!-- elements dependent on checkbox not being checked for server-side
validation -->
<label>Billing address 1:<input type="text" required /></label>
<label>Billing address 2:<input type="text" required /></label>
...
</form>

In a Javascript implementation the billing address fields would be hidden
(display:none) and could be set to @disabled, making them imutable and
therefore not failing the @required constraint validation.

Other than dramatically altering server-side processing mechanisms, and UIs,
how can @required be applied to dependent elements in no-JS clients?
