If Diana had still been the wife of The Prince of Wales and thus the holder of the title of "The Princess of Wales" when she died,wouldn't the title of "The Princess of Wales" be transferred (given) to the wife of the next Prince of Wales (wife of Prince William) instead to the next wife of the current Prince of Wales (Camilla,Duchess of Cornwall)?Since Prince William is not elected as the Prince of Wales and he is not married,shouldn't the title of "The Princess of Wales" be skipped intead of Camilla being called as "The Princess of Wales"?
You seem to misunderstand the concept behind the sharing of titles:
The wife shares all of her husband's titles by courtesy. That means she is not getting these titles of her own, but is allowed to use them as long as she is married to the holder of these titles. There is no title of a "Princess of wales" in her own right, there is only the title of "The Princess of Wales" courtesy of the woman's marriage to "The Prince of Wales".
As long as Prince Charles lives as the heir of his mother, the queen, he is "The Prince of Wales" in his own right, so by courtesy his wife is "The Princess of Wales". If Prince Charles dies before his mother dies, prince William becomes immediately The Duke of Cornwall and The Duke of Rothesay (in the Scottish peerage) plus all Prince Charles' other titles except the title of "The Prince of Wales". It's up to the queen to create her grandson "The Prince of Wales" or not.
When Charles divorced Diana, she stopped being the wife of "The Prince of wales", thus she had no longer the right to the courtesy title of "The Princess of Wales". Important is the "The" - there can only be one "The Princess of Wales" and that is the legal wife of "The Prince of Wales" or his widow, if the next prince is not yet married and is the son of this princess.
Camilla is Charles' legal wife. Charles is "The Prince of Wales". Thus, Camilla is by courtesy "The Princess of Wales" just like Diana was when she was the legal wife of Prince Charles.
The legal wife of the king is the queen - says the law. So when Charles will be king, Camilla as his legal wife will by courtesy be the queen or the queen consort. She is not going to be the queen in her own right, just like she is no princess in her own right.
When "The Prince of Orange" - the heir to the throne of the Netherlands married Ms. Zorreguieta, the queen of the Netherlands created the new "The Princess of Orange" - her courtesy title as the wife of "The Prince of Orange" - into "Princess of the Netherlands" in her own right. If The prince of Orange divorced his wife, Princess Maxima would cease to be "The Princess of Orange" by courtesy, but she would still be "HRH The Princess Maxima of the Netherlands" in her own right. So Maxima's position is much better than that of Diana, who was just by courtesy as wife of a princess called a princess but never was one in her own right. While Maxima now is and will be forever.
As to your question: Prince William's future wife will become "The Princess of Wales" by courtesy the moment her husband wíll become "The Prince of Wales" in his own right. Not a moment before that. As long as Charles lives and is not king, he is the one and only "The Prince of Wales" and his wife is "The Princess of Wales". No matter how she calls herself.
I hope it is clearer now as a concept.
