Localization multi reference

Hi all,

I begin my post saying my excuse for my probably bad english.

So i searched but i never find how i can do a multi reference of ressource file in xaml.

for exemple

i can do that on C#

pagetitle.Text = ResourceStrings.Save + " - " + ResourceStrings.Sport ;

and i don't know if i can do that on xaml and if it's yes i don't know how.

Thanks in advance for help.
