Why not max/min-font-size css properties?

We now have available units based on the size of the viewport.
These units can declare on the size of the texts.
CSS does not have a way to limit the computed maximum or minimum value of
them.

I think you should consider the convenience of including the css properties:
max-font-size
min-font-size
onto the "Css Font module" document.

Thanks and sorry for my english (not my own language)
