XX is not a standard marking. I do not know what you are looking at specifically however; the Gypsum Association has a web site that I use a lot http://www.gypsum.org/. The most common marking for fire ratting is either TYPE X or TYPE C. Look at the GA sit or find the manufacturer site and look for their markings. If the manufacturer does not have a site, it is possible that the product is not listed and should not be used in a rated assembly. Contact your local Building Official or GA for moré information.
