  <my-custom-input name="abc"></my-custom-input>

Right now there is no way to have custom elements include data in form
submissions. We should add another callback for this

I believe we need to add a callback that is called before the submit event.


document.registerElement('input', {
  prototype: {
    __proto__: HTMLElement.prototype,
    beforeSubmitCallback: function() {
      switch (this.type) {
        case 'checkbox';
          if (this.checked)
            return this.value;
          return undefined;

Basically, the contract is that the return value of the callback is used a the
form value. If undefined is returned nothing is serialized.

This is of course a bit too simplistic but it might be enough to get started.

Things to keep in mind:

- Radio buttons need to check outside itself
- input[type=file]. Return Blob|File|data url?
- input[multiple]. Array of values?
