Sec 80gg and form 10ba

I live in a Co-operative Housing society, where I own a flat; I pay my monthly rent to the secretary of this society.  I learnt that form 10BA should be filled and file during the time of filing the return by appending this filled form to the return.  But for ITR forms  ITR 1 to ITR 8 no appended documents are allowed!  I file my return on ITR-2.  What should I then do with respect to form 10BA?  How can I file 10BA?  Or will the data mentioned under chapt VI A deductions 80GG in ITR-2 be deemed legally compliant?  Please reply.  -vrshenoy
