Feature: [up-validate] with different URL about unpoly HOT 3 OPEN

-> Should up-validate be implicitly enabled?

No. It's a modifying attribute of [up-validate].

How should the behavior be on nested up-validate-url?

We cannot easily allow nesting [up-validate-url] as Unpoly 3 batches multiple validations into a single request and guarantees only a single concurrent validation request per form.

See these slides:
http://triskweline.de/unpoly3-slides/#33
http://triskweline.de/unpoly3-slides/#34

If we allowed multiple [up-validate-url] within the same form this gets really complicated really fast.

I like it. It could be implemented by parsing and merging an { url } option here.

Do you think [up-validate-url] or [up-validate-action] is the more intuitive name here? Arguments can be made for both. The render option is actually { url }, but in an HTML form we use [action] to say where the form submits to:

<form action="/form-result" up-validate up-validate-action="/form-render">

Hi @triskweline,

For naming I would argue pro up-validate-url as this is explicitly not about the form action but about an endpoint that validates/renders the form even if technically the form gets submitted.

How should it behave if only up-validate-url is defined without up-validate?
