[boost] [BGL] MutablePropertyGraph questions

Looking at BGL's MutablePropertyGraph docs I can't understand
two things:

     ep is an object of type G::edge_property_type

Is that really so? Why not graph_traits<G>::edge_property_type?

     Edge Property Type
     graph_traits<G>::edge_property_type

     Vertex Property Type
     graph_traits<G>::vertex_property_type

Unfortunately, this description says nothing about that concept
these types model. As the result, I don't know how can I
use 'add_edge' and 'add_vertex' as defined in MutablePropertyGraph.

Can it be clarified?

TIA,
