Missing validation of feature group type declared as inverse

[lwrage]

The AADL text editor does not detect that the features in fg2 don't have the opposite direction of the corresponding features in fg1.

    feature group fg1
        features
            b1: requires bus access mybus;
            d1: out data port;
    end fg1;

    feature group fg2
        features
            b2: requires bus access mybus;
            d2: out data port;
        inverse of fg1
    end fg2;
