Thanks Gaëtan, Michael. I'm afraid I'm still not 100% clear on one point.

Given:

<owl:DatatypeProperty rdf:about="http://example.org/dprop>
      <rdfs:range  rdf:resource="someXMLns:anXMLType">
</owl:DatatypeProperty>

<a:b rdf:about="http://example.org/aninstance">
   <dprop>XXXX</dprop>
</a:b>

Can we actually infer from these statements that  XXXX has datatype
someXMLns:anXMLType?

Or would we still have to explicitly say:

...
<dprop rdf:datatype="someXMLns:anXMLType">XXXX</dprop>
...
?

Cheers,
Danny.
