HTTP API
2. Ripple does not support publishing it as a FPWD of the WPWG at this
time, but may support it in the future once the WPWG can focus on it

Core Messages
3. Ripple does not support publishing it as a FPWD of the WPWG at any
time (unless
a strong case can be made for abstracting the data model from the HTTP API)
