As Kitty described above, the get_XXXconnections method will return a 
sequence of connections which you can use freely. If you want to 
identify these various "facet", one way to do that is to apply some 
application-level mapping mechanism, for example, you can define one 
operation in the facet which returns the component ID, or something like
