This doesn't seem to be simpler than what the draft current suggests:

  <input name="input11" type="integer" step="10" value="20">
  <input name="input11" type="integer" step="10" value="40">

When the wheel is a 300-ton, carbon-bonded, triple-alloy, tapered spoke
mega-wheel with nuclear-powered locomotion, and all you actually want is a
little wooden circle, it is usually best to reinvent it. :-)

I don't understand the benefits of what you are proposing. It would
slightly simplify the life of those wanting to edit documents for which
they already have schemas, at the cost of massively increasing the
complexity for implementors, for whoever writes the test suite, for me (as
the spec editor), and for anyone who tries to learn how it works.

What's the use case for things like this?

Could you explain how a UA would work out what UI to render for a control
that claimed to be of this type?
