The use case is that the Rackspace API supports both XML and JSON requests,
and Nova is supposed to support the current Rackspace API spec.

The Rackspace spec's XML output is basically the RESTful format used by Ruby
on Rails.  The good news is that this format maps closely to JSON or to a
dict; the bad news is that XML requires a bit more information than JSON, so
a regular dict won't suffice on its own.
