Priority: HTTP header or meta tag?

From Yadis

Q:

From Yadis Specification 0.9:

6.2.6 Resource Descriptor URL

...

If the response includes both an X-Yadis -Location response-header and an HTML element whose http-equiv attribute is X-Yadis -Location, either value MAY be used as the the Yadis Resource Descriptor URL.

Note: It is the intent of The Yadis Project to specify which URL should be used in this case. We invite suggestions and rationales from implementers.

So, which is it folks?

A:

Accepting the argument by Larry Drebes, the response-header takes priority.
