W3C validation error: "Bad value X-XRDS-Location for attribute http-equiv on element meta"

I am getting the above validation error in response to the following line in my HTML:

<meta http-equiv="X-XRDS-Location" content="http://www.example.com/wp-content/plugins/socialauth-wp/hybridauth/index.php?get=openid_xrds" />

I use WordPress social auth plugin, that automatically adds this line to the head of every page.

I am not sure what this line does to the site but it throws a validation error.

What does the meta line does to the site, is it mandatory?

I gone through the question Get rid of “Bad value X-XRDS-Location for attribute http-equiv on XHTML element meta.” in XHTML5 validation, but I'm not sure how to register it.

My answer to the linked question applies here, too:

If you use HTML5, you may only use the following values for the http-equiv attribute:

X-XRDS-Location is not defined/registered, so HTML5 doesn’t allow to use it.

What does the meta line does to the site, is it mandatory?

I guess the linked XRDS document is used to discover your OpenID service provider. Or for Oauth, etc..

An alternative may be to send the HTTP header X-XRDS-Location. If you send it, you could remove the meta element (unless some data consumers only look for the occurence in the HTML, which would be a bad practice).
