Add’l guidance re: crew credits/music department

Hi: I am media composer and I have reviewed the policy, help pages, etc. on IMDb‘s policy regarding crew, credits and music department credits, but I am still unclear as to how/whether I can include on an IMDb page/account the music that I have composed for various television productions that are easily verifiable by other sources (e.g., my cue sheets with ASCAP) but are uncredited in the actual productions.  I have found other music composers whose work in this fashion are included on IMDb as “additional music” credits, even though they are not actually named in the credits.  I just wanted to confirm whether this is acceptable per IMDb’s standards/policy.
