Description

A common line of code like this one

 <link rel="preconnect" href="https://fonts.gstatic.com">

is marked as "Bad value" with this phrase:

Bad value "preconnect" for attribute "rel" on element "link": The string "preconnect" is not a registered keyword.
Syntax of list of link-type keywords:
A whitespace-separated list of link types listed as allowed on '<link>' in the HTML specification or listed as an allowed on '<link>' on the Microformats wiki without duplicate keywords in the list. You can register link types on the Microformats wiki yourself.

Actually rel="preconnect" is valid code, as shown here https://www.w3.org/TR/resource-hints/ so should be added to the validator.

I wonder what's and where is the Microformats wiki the message is talking about...
