To specify two or more URI schemes

Is there a way to specify more than one URIScheme in unoproj?

I’m not entirely sure, but isn’t a given app supposed to only have one? If not, could you find and share some links that show how this is handled in native (Java/Objective-C) projects?
Plus, perhaps you should do so in a ticket on fuselibs, so that the community can pick this up.
