Do you mean you don't have the C++ Standard, or that your copy
doesn't have section 14.6.2(3)?
Here is what it says:
In the definition of a class template or in the definition of a
member of such a template that appears outside of the template
definition, if a base class of this template depends on a
template-parameter, the base class scope is not examined during
name lookup until the class template is instantiated.
[Example:
typedef double A;
template<class T> B {
typedef int A;
};
template<class T> struct X : B<T> {
A a; // a has type double
};
The type name A in the definition of X<T> binds to the typedef
name defined in the global namespace scope, not to the typedef
name defined in the base class B<T>.
]

I don't know why this section was written that particular way,
but there probably was a good reason for this, since this is
somewhat unexpected. The reason possibly has to do with the fact
that template specializations can almost completely change class
interface.
Language experts over in comp.lang.c++ may have a ready explanation.
