Yes, and before 1.0.

Oh, nice.

One thing though: we have discussed whether it would be better to have "all=
ows=20
value" available for every type. The current Enum then would rather be a=20
Type:String with allows value set. But all other types could allow similar=
=20
features, and we would get rid of Type:Enum completely. I guess your patche=
s=20
could still be used as a basis for all other types as well (or, for a start=
,=20
for Type:String).
