annotate same data with different vocabularies

Hi all,

could someone give me an example how to write something like this:

<div about="#meri" instanceof="foaf:Person vcard:Name">

 <span property="foaf:firstName vcard:Given">
     Meri
 </span>
 </div>

I want to annotate my name with properties form two different vocabularies.

Thnx,

Meri
