RE: [sv-ac] strange example

John,

It is legal to have a default parameter value which will not be legal in
elaboration. That is a way of forcing the user to redefine the value in
the element instantiation.
An example is in 24.5.4 in the line

// Bus interface with parameterized number of client modports
interface intf_t #(num_clients = 0);

But that does not mean it should be done in this example.
