Since context is a void *, it also seems best practice to just use some unique pointer values. For example, mmalc's Graphics Bindings sample does this:
static void *PropertyObservationContext = (void *)1091;
static void *GraphicsObservationContext = (void *)1092;
static void *SelectionIndexesObservationContext = (void *)1093;


Sorry about that -- I think I put them in there originally when I was testing things, and they stuck.
Fixing them now...
