Yadis Spec .9 Change Proposal: Sect 6.2.6

[Larry Drebes]

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.
