[dmitshur] https://microformats.org/wiki/h-card describes `u-uid` property as "universally unique identifier, preferably canonical URL". Is it meant to be a unique identifier for the person the h-card describes, or for the h-card itself? Is there a way it differs from `u-url`, which is described as "home page or other URL representing the person or organization"? What benefit is there in specifying `u-uid` compared to leaving it out?
