Henri M. said:
This is exactly why in 2002 in the Netherlands the titulature in the royal house was made 'gender free' and equal in all cases. Also is fixed by law that the spouse of the Sovereign and of the Heir-Apparent, no matter the gender, is given the own title of Prince(ss) of the Netherlands. Copy and paste this to the Swedish situation:
H.M. Sveriges Konung
H.K.H. Sveriges Prinsessa
H.M. Sveriges Dronnung
H.K.H. Sveriges Prins
H.K.H. Sveriges Kronprins
H.K.H. Prinsessa {...name...} av Sverige
H.K.H. Sveriges Kronprinsessa
H.K.H. Prins {...name...} av Sverige
If the Swedes would take over the new Dutch system, then Victoria and Daniël would become:
H.K.H. Sveriges Kronprinssessa, Hertiginna av Västergötland
H.K.H. Prins Daniël av Sverige
and later
H.M. Sveriges Dronnung
H.K.H. Sveriges Prins
