Hi,

I am wondering how I can assign a Vector3 (eg. float val[3] or float 
x,y,z) to a property in a graph that is read in from a graphml xml file. 
I can easily set 3 properties, x,y,z but then I have to create a graph 
that is read like this:

    typedef property<vertex_x_t, float> x_coord_t;
    typedef property<vertex_y_t, float, x_coord_t> y_coord_t;
    typedef property<vertex_z_t, float, y_coord_t> coord_t;

    typedef adjacency_list<vecS,vecS,directedS,
        coord_t,
        property<edge_weight_t,float> >    graph_t;
   
    graph_t g;
    dynamic_properties dp;
    dp.property("x",get(vertex_x_t(),g));
    dp.property("y",get(vertex_y_t(),g));
    dp.property("z",get(vertex_z_t(),g));
    dp.property("weight",get(edge_weight_t(),g));

    std::ifstream ifile(path.string().c_str());
    read_graphml(ifile, g, dp);

I would much rather be able to set a property of type Vector3 and not 
have to convert from the above code to a new graph whose vertices have 
Vector3 properties attached.

thanks.
