It is only a very basic implementation, because not every element is accessible through actions or filters. It is better to use a theme that supports <a href="http://microformats.org/wiki/microformats2" rel="nofollow ugc">Microformats 2</a> fully.

This plugin extends the standard WordPress profile to inclue additional 
attributes such as photo, organization, address, phone number, and others. A 
user’s entire profile can then be output as an <a href="http://microformats.org/wiki/hcard" rel="nofollow ugc">hCard</a> on any page using the 
 profile shortcode, or with the provided widget.

Extended Profile

Extend the WordPress profile to include additional attributes, and output as hCard.
