The advantage of using x-data here is so that x-data compliant clients do not
need to implement yet another namespace for just a simple form. X-Data is
perfectly suited for this type of operation. It's also not JUST a yes/no since
the approver probably wants to see who the requestor is, and what NODE they are
trying to subscribe to. Thus, there is a some basic information that needs to be
displayed to the approver. In general, it's just not necessary to force clients
to implement yet another bit-o-protocol, when we already have something that can
be used. Re-use of protocol is a GOOD thing :)
