How are Margriet's Sons Princes?

I thought, per Royal rules, you were Prince(s) or Princesses(s) if your FATHER was a prince unless your mother was the heiress to the throne. So, how is it that these boys are all styled as Prince this or that? Does this apply to all of Beatrix sisters?

Because when the Parlieament was dweciding about the Bill consenting the marriage of Princess Margriet and Pieter van Vollenhoven it was agreed that their children shoulc have the title Prince of Orange-nassau and the name van Vollenhioven withn the style of Highness. Margriet was after all second in line of succession at that time.

Only the children of Princess Irene are also Prince/Princess but not because of their mother it is because Irene married a Prince.

It was decided by parlament indeed, it was said that Queen Juliana really wanted ALL her grandchildren to be princes and that she was slightly upset that the van Vollenhoven's only became HH's, thus creating A-princes and B-princes. In Belgium princess Astrids children have the same titles as those of Philippe and Laurent at the moment.
