Jan,

It's quite common in HTML documents to have multiple <link> headers with the
same "rel" value pointing to different information, such as including
multiple CSS documents.

That said, what would a browser do if it sees multiple <link> relations for
a shortcut icon?

Perhaps the answer to your question is "it depends" :-)

Paul
