  registry: Parse “popularity” attribute Previously the attribute “popularity” was completely ignored. It also did not respect the modified DTD, because its default value depends if we are currently parsing an “extras” rules file. Fixed: - Always parse the popularity attribute. - Change the DTD to reflect that the default value is implied.
