Manage "action" and "formAction" route dispatch

[dupuchba]

When writing forms that redirect to a route if successfull, I find out that I can't write valid/SEO compliant HTML by using classical anchor.

I need to dispatch route on the action/formaction attributes.
I no that pushy only filter a/href ; what do you think about opening it to action/formAction

• action on form element
• formaction on button

Thanks for your advices
