Property talk:Equivalent URI

When I put the next wiki code:

 {{#set: equivalent URI=http://www.w3.org/2000/01/rdf-schema#label}}

and load the page. The SMW engine shows a yellow admiration in the Fact Box with the next text: URIs of the form "http://www.w3.org/2000/01/rdf-schema#" are not allowed.

Can anyone reproduce the error? Does anyone know how to resolve the problem?
