It is used for the signature header, so it is a multiple-type signature
there. However, I think it isn't allowed to have multiple types when
it's the signature of a variant. Don't remember for sure. If so, it
sounds like for your usage you can just assume the signature of a
variant has only one type in it.
For the glib bindings generically perhaps you could just marshal as a
GType if only one type, and as an array of GType otherwise, and app
authors can just handle both cases?
