Draft spec text for HTTP Headers

Using GRDDL With HTTP Headers

To accommodate XML dialects that do not have the necessary extension
mechanisms in either their schemas or instances we can use HTTP headers
to specify the necessary profile and transformation. 

To associate an instance document with a GRDDL transformation include a
Link and a Profile header in the HTTP message. The Link header contains
the URI of the transformation and a "rel" parameter having a value of
"transformation". The Profile header contains the URI of the GRDDL
profile http://www.w3.org/2003/g/data-view


An example HTTP Message 

This HTTP message is the response to a request for the document at
http://example.com/doc
