Yes, this approach is probably the easiest. Simply derive your own exception
class from schema_exception like this:

#include <xsd/cxx/parser/schema-exceptions.hxx>

struct my_exception: xsd::cxx::parser::schema_exception<char>
{
  virtual std::string
  message () const
  {
    return "...";
  }
};

And throw it from one of the callbacks. You should then see the message along
with the file/line/column information as if it was an XML validation error.
