Currently, the marriage certificate tag is used to refer to both fictional marriage certificated for characters (e.g. post #356975, post #483732) and for certificates that appear as objects in an image (e.g. post #459969, post #1805625). The wiki refers solely to the former use. I was considering splitting the latter usage into a new tag, say, "marriage_certificate_(object)" for consistency with other such tags (see also: dakimakura vs. dakimakura (object)), but wanted to get more opinions on it before splitting it off.
