Ok, I understand that "http://www.w3.org/2002/03owlt/SymmetricProperty/premises001#premises001#path" is not a valid URI, and if I read the "RDF/XML Syntax Specification" correctly, the fact that "a fragment identifier is transformed into a RDF URI Reference by appending the fragment identifier to the in-scope base URI" means I have to extract the fragment identifier "#path" from the identifier before concatenating it with the base URI.
