Question on the REST Profile, XML, and JSON

Hi all, Ray,

Looking back at the REST profile of XACML, you define 2 HTTP headers:

Content-type

Accept

According to the HTTP spec, the Accept request-header field can be used to specify certain media types which are acceptable for the response.

The Content-Type entity-header field indicates the media type of the entity-body sent to the recipient

Does it mean I can send a JSON XACML request and have Accept set to XML in which case the PDP replies with an XML encoded XACML response? And vice-versa? Should we explicitly prevent that? Is there a good use case?

Cheers,

David.
