For those unaware, in content negotiation (Accept), A userAgent can specify
_multiple_ representations in weighted order:
Which informs the server, that the user agent wourl prefer
application/xrid+xml (this is the 'official' XRID media type, though IANA
registration is pending until the resolution spec is final).
Not sure this sways anyones thinking, but it is not a oft-used capability
