Is it possible to include more than one link tag in an HTML document with the same rel="..." value?

Question

I am using the default wordpress theme (twentyseventee) and I see that the header includes the following:

<link rel="profile" href="http://gmpg.org/xfn/11">

I would like to also use the hCard microformat to describe my info (photo, name, email, etc.) However, the hCard requires the following link:

<link rel="profile" href="http://microformats.org/profile/hcard">

Now I am thinking that if I have two links with rel="profile" it is very likely that the search engines will drop one or the other.

Is there any information about that somewhere?

Answer 1

This answer has some pretty good information about that.

rel="profile" was dropped in HTML5, it may not be of a whole lot of use anymore. While it may be more useful to some of your users with older browsers, most search engines are probably disinterested with it now.
