I think the default for preferred value is "initial value" -- if it applies to padding it will be '0', not 'auto'.

It may be a good idea to not allow flex(1 auto 0). It is just weird. Can we say that if there are two non-negative numbers they must be together? I think there is precedent in background shortcut property.

For unitless length, it may be OK to require '0px'. It can also be defined that if there are 3 numbers, the last one is the preferred length (then the first two are never ambiguous).

The rest looks good to me.

I've altered the draft accordingly.  Do you mind checking to make sure it looks good, Alex?
