Hello Daniel,
Just too questions that still are unclear for me:
1. Why does all compile and work fine with attached 
boost/graph/properties.hpp ?

2. Why do I have compilation error when trying to get "const_type" map 
for graph  with "basic_vertex_properties<>" as vertex property class ?
/////////////
boost::property_map<adj_list1_t,
basic_vertex_properties<>::node_name_type basic_vertex_properties<>::*
 >::const_type 
node_name_map1(boost::get(&basic_vertex_properties<>::m_node_name, c));
////////////
(see details here http://lists.boost.org/boost-users/2006/02/17168.php )
