I=E2=80=99m afraid there isn=E2=80=99t any definite published description=
 of exactly=20
what the CSS Validator is checking against. But it seems that (possibly=20
with some exceptions) it recognizes W3C CSS specifications with maturity=20
level CR (Candidate Recommendation) or higher.

And as far as I can see, :required is not defined in such documents.
=E2=80=9CSelectors Level 4=E2=80=9D mentions it, but it=E2=80=99s just a =
Working Draft and has=20
not made much progress (the newest Working Draft is dated 2 May 2013).

I wouldn=E2=80=99t expect so. But why would that matter?

There is the simple workaround you mention, using the attribute selector=20
[required]. (I wonder whether :required offers any particular benefit=20
over it.)
