You would then need to walk the vertex and edge properties of the two 
graphs; note that bundled properties can't be enumerated in this way and 
that the properties may be in different orders for different graphs.  I 
don't think there is a portable way to get the information you want, 
though.  You might need the user to specify how they want each property 
handled; for example, a property that only exists in one graph might be 
filled in with a default value when the other graph is put into the 
output.
