Constraint on Composite Type

How can I create a constraint on a sub-field of composite type?

Pseudocode

create type axis(
    major_axis float,
    minor_axis float,
    angle float constraint angle_constraint check(angle between -90 and 90)
);

create table sample(
    axis1 axis,
    axis2 axis
);

Is this possible in PostgreSQL 9.2? It seems to be not possible in 9.1 as mentioned here.
