I assume you realize that if you have two such schema files that map to
the same C++ namespace, you will get duplicate symbols down the line.

If you still want this, what prevents you from opening the namespace
in prologue/epilogue? If you don't want to hard-code C++ namespaces 
in the command line, your script can extract the targetNamespace 
attribute just as it does for version. You can then map it to a C++ 
namespace similar to how XSD does it.
