What is the "X-XRDS-Location" attribute used with the meta tag in HTML?

I was looking at some source for a webpage and saw this:

<meta http-equiv="X-XRDS-Location" content="xxxx.php">

What exactly does this do and what is the point?

Thanks!

XRDS (eXtensible Resource Descriptor Sequence) is an XML format for discovery of metadata about a resource – in particular discovery of services associated
with the resource, a process known as service discovery. For example, a website offering OpenID login can resolve a user's OpenID identifier to an XRDS document
to discover the location of the user's
OpenID service provider.
