With this convention it becomes effectively impossible to have a 
language independent default version. With the following illegal rdf/xml 
I'd like to express that the default abnormal-termination message if 
"Requiem in pax" which are Latin words, but the English version is a 
blinking "Rest in peace".

    <ex:abnormalTermination rdf:parseType="Literal"><span
         xml:lang="la">Requiem in pax</span></ex:abnormalTermination>
    <ex:abnormalTermination xml:lang="en" 
rdf:parseType="Literal"><blink>Rest in
