schema.org+Microdata: additional namespaces?

Dear all,

is it possible to use properties from another namespace (like Dublin 
Core) together with schema.org in Microdata? Using the Avatar example on 
the schema.org website (http://www.schema.org/docs/gs.html) would the 
following example work?

    <div itemscope itemtype ="http://schema.org/Movie"
    itemid="http://dbpedia.org/resource/Avatar_(2009_film)">
        <h1 itemprop="name
    http://purl.org/dc/elements/1.1/title">Avatar</h1>
    </div>

Or translated into turtle:

    <http://dbpedia.org/resource/Avatar_(2009_film)> a  schema:Movie ;
    schema:name  "Avatar" ;
    dc:title "Avatar" .

Best wishes,
Cord
