We've got no option really, that's what vCard forces us to do. :(

While you're thinking about vCard stuff, I want to replace the
ContactInfo interface with something more Telepathy-like, where user
information is represented by a dictionary of strings to variants.
Exposing the clients to vCard-temp XML is horrible, so I've actually
disabled that code in Gabble.

Something like:

GetInfoFields () -> a{sg}
RequestInfo (u: contact) -> a{sv}
SetInfo (a{sv}: fields) -> None

And just define some well known fields, name, address, phone, email, yada.
