That's a good example. So with a current approach it's just not possible to 
handle such cases. Shall we change it so that the type is internet/wap/mms and 
the plan is contract/prepaid? Should then "type" and "plan" be optional or 
mandatory?

Does anyone see any problems with this approach? Have we missed any other use 
cases or alternative solutions?

Oleg
