Concept Check - Newbie Question

I am playing around with the Concept Check classes, and trying to get
the following code to compile.  All I want to check is if the type is a
std::vector and contains unsigned chars.  What am I doing wrong?  I am
trying to compile on VS.Net.

Thanks in advance for your help!

#include<vector>
#include "boost\concept_check.hpp"

template <class OutputVector = std::vector<unsigned char> >
class Test
{
    BOOST_CLASS_REQUIRES(OutputVector,
boost::ConvertibleConcept<OutputVector::value_type, unsigned char>);
    BOOST_CLASS_REQUIRES(OutputVector,
boost::RandomAccessContainerConcept<OutputVector>);    
};

int main(void)
{
    Test t<>;
    return(true);
}
