     In the proposal, 12.4 para. 1 says,
     
     "Generate constructs provide the ability for parameter values to affect the structure of the model. They also allow for modules with repetitive structure to be described more concisely, and they make recursive module instantiation possible."
     
     A paragraph in 12.4.2 also says,
     
     "Conditional generate constructs make it possible for a module to contain an instantiation of itself. The same can be said of loop generate constructs, but it is more easily done with conditional generates. With proper use of parameters, the resulting recursion can be made to terminate, resulting in a legitimate model hierarchy. Note that because of the rules for determining top-level modules, a module containing an instantiation of itself will not be a top-level module."
     
     I did not find other references to it, though I might have missed one.
     
     One might conclude from this that a recursive instantiation using configurations might not be legal, though.
     
     Shalom
