MCA recently introduced the Companies (Filing of Documents and forms in XBRL) Rules 2015 dated 9th September 2015 for which I have yet to locate published copy in the Official Gazette. These rules shall come into force from the date of publication in Official Gazette. These rules have already discussed earlier here.
Note: AOC – 4 XBRL Version 1st October 2015 is being used for writing this post.
