[whatwg] <input type=number> without keyboard editing

[TAMURA, Kent]

A team in Google tried to use <input type=number> for a product, and they
decided
not to use it.
What they needed was a control to select an integer from a specific integer
range
such as 1 - 16. The number type control in Opera and WebKit allow a user to
input
out-of-range value even if the control has min=1 and max=16 attributes.
It's not
a good UI and the reason why they doesn't use type=number.

They need a number control which
   - doesn't allow any keyboard / cut&paste operations and
    So, a text field part is read-only, but the spin-buttons work.
   - always has a valid value.
    "required" by default, and sanitization algorithm may be different.

I'm not sure how to solve this issue.  Introducing new content attribute or
another number type?
