Age certificates for music videos and Iconography

I put in a post earlier of the year that i would like my age certificate to be a 12. This is to make the audience larger but still have the ability to swear. For music videos they currently don't have a system to put certificates. This means that i could put anything on my video and anyone could watch it. This is not the aim as i don't think kids under the target audience would not understand the storyline. David Cameron is currently trying to get a system as you can see in this article.

This slide share is explaining the certificate i would give my music video and is also about iconnography.
