No, this is not valid for a simple reason that std::vector is a template
that has more than one argument. Your 'ContainerTemplate' template
template argument has only one argument itself.
Until we have template typedefs you're probably out of luck. You could
try declaring your own template deriving form 'vector<T>', but you'd
have to duplicate all functionality.
