1. Are Articles 1(u)(i) and 10a and Annexes II and IIa of Regulation (EEC) No 1408/71, which lay down the principle of the non-exportability of childbirth and maternity allowances, consistent with Articles 48 and 51 of the EC Treaty?

Is Regulation No 1408/71 to be interpreted as meaning that, in respect of dependent children, it grants workers in receipt of an invalidity pension who reside in a different country from that which pays the invalidity pension, family allowances only, to the exclusion of the child-raising allowance which is not granted by reference to the number of children?
3. Is Article 73 of Regulation No 1408/71 to be interpreted as meaning that the recipient of an invalidity pension who continues to make compulsory sickness insurance contributions in the country which provides the pension, may, notwithstanding his pension, be considered in that country as an employee who is entitled to receive family benefits, including the child-raising allowance, and - in the event that the non-exportability clause is held to be incompatible with the Treaty - childbirth allowances?
4. Does the concept of "worker" within the meaning of Regulation No 1612/68 include the recipient of an invalidity pension who resides in a different country from that which provides the pension?
