RE: tracking-ISSUE-120: Should the response header be mandatory (MUST) or recommended (SHOULD) [Tracking Preference Expression (DNT)]

I believe draft text has already been provided for this issue - was this opened to track it separately?

<Sent by Matthias on 1/19>

--------------------------------------
A site that receives DNT;1 MUST follow the corresponding practices as defined in the [standards compliance] document and SHOULD send a corresponding DNT response header.

Note: If a site chooses not to send a response header, then the user agent does not obtain information whether the preference has been accepted or not. This may have negative consequences for the site such as:
 - Preventive measures by user agents
 - Being flagged as non-compliant by scanning tools that look for response headers

Raised by: Matthias Schunter
On product: Tracking Preference Expression (DNT)

We had discussions whether the response header should be mandatory (MUST; A site not sending a header is deemed non-compliant) or recommended (SHOULD; user agent cannot derive compliance but will usually assume non-compliance if header is missing).
