Sect 6.2.6

From Yadis

Section 6.2.6 contemplates the case where a X-YADIS-Location header exists and a HTML <meta> tag also exist.

We feel strongly that the header if present should always be used, regardless if there is a <meta> and/or the <meta> value differs.

This approach makes the behavior when processing the results of both HEAD and GET requests consistent. If a GET request prioritized the <meta> tag, it would be prioritizing information not available to HEAD requests. It seems highly desireable to make the two as consistent as possible, which means prioritizing the HTTP response header.

Done.
