[Bug 7697] The type attribute should ammend the Accept header accordingly. HTTP spec is in accordance with the rules here, in terms of the Accept header being non-authorative. script and style elements already ammend accept header (in firefox) but not for other link

Ian that would appear to be incorrect given that, according to the HTTP spec,
the Accept header is simply intended to indicate the appropriate media types
for a response to a given request:

http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html

"The Accept request-header field can be used to specify certain media types
which are acceptable for the response"

So, the value of the Accept header should be taken (if specified) from the type
attribute for a given hyperlink element - which is presumably why firefox
modifies the accept header for the style and script elements.

This allows hyperlinks to specific representations that must be negotiated via
HTTP content negotiation - as it stands, it is not possible to specify such a
link with HTML5.

i.e. currently - these links would actually generate identical requests with
the same Accept header: 

<a type='application/xml' href='/document'>document in xml</a>
<a type='application/json' href='/document'>document in json</a>

If implemented any existing mechanisms which disregard the Accept header would
remain unaffected by the change. 

If no type is specified then default UA Accept header value should be assumed.
