    Yes, it does seem to be contradictory regarding the possibility of declaring
    a parameter within a generate. I see that I also had circled the words
    "declared within the generate scope" on one of my copies, so it seems I had
    noticed it at one time also.

    Be that as it may, the correct interpretation is that a parameter declaration
    may not appear within a generate. However, a generate may instantiate a module
    whose definition contains a parameter declaration.

    In any case, we are already in an advanced complete rewrite of this section.
    Thanks for your comments.

    Shalom
