Never was possible - users are just too inventive. Instead, look at it the other way. Find the set of all things that are _valid_ RSS and exclude anything else. This is a smaller set than the invalid stuff, and it's better documented. If you _only_ allow the valid sequences, then you have implicitly forbidden all the invalid stuff.
