[whatwg] <input> value sanitization algorithm

[Jonathan Watt]

In addition to the value sanitization algorithm, some input types specify 
actions that the user agent must take when the element's value is suffering from 
underflow/overflow or a step mismatch. To make it clearer that these actions 
will also be run when the value sanitization algorithm is run, could the text be 
changed to include each type's underflow/overflow and step mismatch actions 
under the the respective type's value sanitization algorithm?

(Otherwise it's unclear to me why some of the steps that are applied when 
converting the value content attribute to the input element's value have this 
special "value sanitization algorithm" label attached to them, while others do not.)
