I've already come up with a way, any template with the @rtInfo UDA is 
treated the same way as RTInfo is now. The problem is then how to store 
the data in TypeInfo. Since it would be possible to have multiple data 
generated for a given type I was thinking it could be stored in an 
associative array. The keys would be the name of the module which 
generated the data and the the values would be the data.

Something like this:

module foo.bar;

@rtInfo template Foo (T)
{
     enum Foo = "bar";
}

assert(typeid(T).rtInfo["foo.bar"] == "bar");

If I recall correctly Martin Nowak didn't like this approach. The 
associate array would need to be built at load time of the application 
due to separate compilation.

BTW, here [1] is the pull request and the reason why it was closed.
