This is difficult to do in practice.  Consider:

  <input type="number" min="20" max="50" value="20">

The user now wishes to input 30 instead of the default value of 20. 
What steps need to be taken to do this, and how does the input control 
react to those steps?

I agree that things are simpler if only one of min and max is specified.
