Queries relating to certificate of practice

I have one doubt regarding formation of Cost Accountant (ICAI CMA) firm in association with one Chartered Accountant. Earlier I thought that Its not possible to form firms with other professions (except via, LLP). But recently I have gone through the notification issued by ICAI Notification No. 1-CA(7)/116/ 2008 dated 25-9-2008, permitting CAs to enter into partnerships with non-CAs (CMA,CS etc). Can you please provide me a clear cut answer for my humble request.
