@param epr The EPR of another resource which may be the same as this resource.
@return True if the two resources are the same according to their WSDM ResourceId values or their WSDM CorrelatableProperties expressions. Note that if the method returns 'false', this does not guarantee that the two resources are actually different - you can only confirm this by checking with the hasNegativeAssertions() method.
@throws SoapFault
- If there is a problem reading the correlatable properties from either resource.
- If the values or dialects of the correlatable properties are not supported. The built-in dialects are WSDM Property Boolean Match (PBM) and XPath 1.0.
