Yes. The draft standard defines a string class called "string", and
all library elements are in the "std" namespace. You have basically
three ways to access names in the standard library:
1. Explicit qualification:
	std::string MyString;
2. A using-declaration:
	using std::string;
	string MyString;
3. A using-directive:
	using namespace std;
	string MyString;

The using-declaration (#2) places the specified name in the current scope
having its original declaration.

The using-directive (#3) makes all names from the namespace visible from
the current scope, which is subtly different from placing those names IN
the current scope. (And subtly different from placing them in a notional
surrounding scope.) See Stroustrup's "Design and Evolution of C++" for
more details.

Your typedef is a variation of #1.
