[Boost-users] BGL - edge descriptor and map

I'd like to specify better my problem. I'd like to use an 
edge_descriptor (graph_traits<G>::edge_descriptor) as key in a map. The 
graph type is something like this:

typedef adjacency_list<vecS, vecS, bidirectionalS,
          no_property, MyStuff> G;

I think that I've to overload the < operator for 
graph_traits<G>::edge_descriptor. Is this correct? If so, given two 
edge_descriptors I need to access the source and the target of the edge 
in such a way to define a sort ordering.

Thanks,
Giulio
