Document Request & Response Headers in WebAPI

Question

I've developed a WebAPI service which passes Request & Response headers for each controller (globally). Does the WebAPI HelpController support documentation of these, through HttpResponseMessage and Requests?

Example Request Headers;

Content-Type: application/xml; charset=utf-8

Example Response Headers;

X-Rate-Limit-Remaining: 1000

X-Rate-Limit-Limit: 1000
