:: I think that such information is not in the scope of this article. For instance, we do not go into the detail of how JPEG compression works in this article, or how auto focus works. This information is included in other articles. If a reader wishes to know more on these subjects they can find it in those articles. Last time I checked, wikipedia had no obligation to include legal information relevant to different aspects of the subject that article was describing. For instance, we do not talk about that people should not use the 7D to reproduce copyrighted work, like a painting. Nor do we describe that a photographer needs to get a model release in certain jurisdictions, in order to make commercial use of persons image. I do not agree with this informations inclusion in this artcle.
