Resolution status:

* HTTP responses and linked resources:
I understand the LINK_TARGET_FORMAT test as willing to return WARNs to the user on linked resources, and to never return any FAIL. However, there are several cases in the tests that should be carried by the checker for HTTP responses that return a FAIL, even when the resource is a linked resource:
- "If an HTTP request does not result in a valid HTTP response [...], FAIL"
- 1 case in "If the response is an HTTPS response"
- 2 cases in "If the HTTP status indicates redirection"
- "If the HTTP status represents failure (4xx), other than 404 or a request for authentication (e.g. 401), FAIL"

I guess one may argue that LINK_TARGET_FORMAT may return a FAIL message.
The last point still stands in that case: is a linked resource that
returned a 406 Not Acceptable status supposed to trigger a FAIL? I think I should be allowed to include links to external resources that are not able to serve content to the mobileOK checker in a page without losing the possibility for the page to be mobileOK. I would relax the last check to state:
"If the HTTP status represents failure (4xx), other than 404 or a
request for authentication (e.g. 401):
If the response relates to a request for a linked resource (see 2.4.7 Linked Resources), continue with the test (see 3.10 LINK_TARGET_FORMAT ) and warn
Otherwise (i.e. for included resources), FAIL"
