Technically, contrary to Ive's claim (who is usually right in such
things), the sRGB color space _is_ well-defined(*) for values outside
the 0..1 range, both positive and negative.
The official sRGB specification (v1.10) refers to limiting the color
values to the 0..1 regime as "typical", and _in such cases_ mandates
that simple clipping is to be used for this purpose, but there is no
provision mandating gamut limiting _per se_, and there is no fundamental
mathematical problem with the functions outside the range.
(* Note that I'm not saying well-suited. That would be an entirely
different discussion.)
