Win7 CamiTK env is deployed with xsd 3.3 which does not have the std option. xsd version is checked and if it is at least 4.0.0, option "--std c++11" is used to generate the C++ source code from the XSD documents. This results in a strict C++11 code that does not generate compiler warning on modern c++ compiler (mainly due to the generation of C++98 "auto_ptr" instead of C++11 "unique_ptr")
