Unknown rule

Dear all,

 

Can anybody tell me why the following doesn't pass any RDF validator?

 

xyz:P-101/40000512  ex:propertyValueInBarGauge   "14,7"^^xsd:decimal . 

or

xyz:P-101#40000512  ex:propertyValueInBarGauge   "14,7"^^xsd:decimal . 

 

It seems to me that the subject is a perfect URI, but apparently it violates
some rule.

But no validator tells me which rule.

 

I got:

Unexpected "string" on line 208.

Syntax error: unexpected "string" on line 208.

Error! $resource should be either IRI, blank-node identifier or
EasyRdf_Resource. got empty string 

 

Please enlighten me!
