The use of the value production from 2.1 isn't desirable in any case.
What we actually want to do is simply say that it has no grammar -
that every possible property value is valid for a custom property.
That way, the only limitation is what is automatically imposed by the
parser itself.

Pending dbaron's review and hopeful approval of Syntax, I'll switch
Variables over to a definition like that.
