owl:sameAs assertions in RDFa

hello all

I am trying to make an owl:sameAs assertion in some RDFa but when I test 
it only the first statement (rnews:about bbc:thing) is being picked up, 
the owl:sameAs to the corresponding dbpedia URI is being ignored:

<span rel="rnews:about" 
resource="http://www.bbc.co.uk/things/4c0ccb99-7042-49e5-bb44-338b540441eb#id">
     <span rel="owl:sameAs" 
resource="http://dbpedia.org/resource/Buckinghamshire_County_Council"></span>
</span>

(I have declared the rnews and owl prefixes elsewhere in the doc)

Anyone tell me what I'm doing wrong here?

thanks

JT
