I also agree with Tab and Jeremy on this one - that makes a lot more
sense to me and removes any ambiguity without being overly verbose.

> I asked:
>> Related question: do we still want to keep this unit-less i.e. ditch the "px" from the examples above? Or, if we're going to use this CSS-like syntax anyway, allow other units of measurement (e.g. ems).
> And Tab replied:
>> No, if we're aping the CSS syntax more closely, we should just use CSS units.
> I agree. Seems like the sensible approach. It also allows authors who are using ems for their media queries in CSS to also use ems for their srcset declarations.
