Can you elaborate on this?

Are not you supposed to provide an explicit initialization for the
type_id<T>::value for every T you are using and that would be the only
instance?

I can not find anything in the standard that would contradict your
statement, at the moment, except that if you treat a template
instantiation as a class in this case you may say that 9.4.2 para. 5
applies to template instantiations and then there should be no more
than once instance of a static member for a particular set of template
arguments.
