The simple_type type has the default c-tor which should be used in this
case:

date::
date (const gregorian::date& d)
  : gregorian::date (d)
{
}

You need to implement serialization operators for the custom date type,
something along these lines:

namespace xml_schema
{
  void
  operator<< (xercesc::DOMElement& e, const date& d)
  {
    e << to_extended_iso_string (d);
  }

  void
  operator<< (xercesc::DOMAttr& a, const date& d)
  {
    a << to_extended_iso_string (d);
  }

  void
  operator<< (xml_schema::list_stream& ls, const date& d)
  {
    ls.os_ << to_extended_iso_string (d);
  }
}
