Can Catholics receive communion in an Anglican Church?

Just to set the record straight, this is the Anglican Policy, at least in the jurisdiction of Anglican churches I belong to (the A.P.A.): Anyone who is a Baptized Christian, Confirmed by a Bishop in Apostolic succession and believes in the Real Presence of Christ in the Sacrament can receive Communion.
By this, someone who is a member of the Roman Catholic and an Eastern Orthodox church can receive communion because the teachings of these churches are in agreement with the three conditions stipulated.
The only thing that would prevent a member of the Roman Catholic or Orthodox churches from receiving Communion is their conviction, because of the teachings of their respective churches, that Communion in the Anglican Church is not a valid Sacrament.
And I believe most, if not all, Continuing Anglican Jurisdictions have the same policy.
