Except for tags, which are datatype properties and visible to reasoners,
so due care is called for. Good news is, I tried Pellet and it didn't
blink an eye: a slight variation of DR example 2-14 where the definition
of tagset_1 goes like

    <owl:intersectionOf rdf:parseType="Collection">
      <owl:Restriction>
        <owl:onProperty rdf:resource="http://www.w3.org/2007/05/powder-s#tag" />
        <owl:hasValue xml:lang="en">New Releases</owl:hasValue>
      </owl:Restriction>
      <owl:Restriction>
        <owl:onProperty rdf:resource="http://www.w3.org/2007/05/powder-s#tag" />
        <owl:hasValue xml:lang="nl">Nieuwe Releases</owl:hasValue>
      </owl:Restriction>
    </owl:intersectionOf>

works just fine (that is, our Semantic PP returns both wdrs:tag triples
with their xml:lang attribute).
