[Idea]: Integration of Error Result with RFC 7807 standard format

[zenkraker]

Hi,

I was interested into integrating the error format as the RFC specification 7807 that basically is a standard format to return errors on an REST API. If you find it interesting we could have a discussion on how to implement this (maybe that would be just an extension/optional feature).
In the link below you can find some more info about it:
