One module cannot then safely reference class mod without either assuming that it has already been declared (with correct parameters) or assuming that it must be declared (in which case the needed parameters must be provided). Neither assumption is safe in general unless you put in a lot of work to make it so.
That's more an indictment of the state of parameterized classes in Puppet 2.7 than of your architecture, but you should nevertheless take it into account as you plan how your modules will be structured.
