<form action="/accounts/create" method="post" id="create-account">
    <fieldset>
      <label for="email">email</label>
      <input type="email" name="value[email]">
    </fieldset>

    <fieldset>
      <label for="username">username</label>
      <input type="text" name="login[basic][username]">
    </fieldset>

    <fieldset>
      <label for="password">password</label>
      <input type="password" name="login[basic][password]">
    </fieldset>

    <fieldset>
      <label for="admin">
        <input type="checkbox" name="value[admin]">
        admin
      </label>
    </fieldset>

    <div class="form-actions">
      <input type="submit" value="Create your account">
    </div>
</form>

Then we get the { login: {}, value: {} } object ... ?
