Resource getLocalName() and number in URI fragment

Helllo everybody.

I have a number of classes that have a URI with a number in fragment
like the following: http://www.semanticweb.org/ontologies/2012/lala#2013.

In this case using getLocalName() on this specific OntClass
returns an empty string"". Is this a valid behavior?
I was expecting it to return "2013".

Thank you.

getLocalName() returns the best localname compatible with RDF/XML that 
it can.

qnames in XML can't start with a digit (prefix names in turtle can) so 
getLocalName() is deciding the URI is best split as:

"http://www.semanticweb.org/ontologies/2012/lala#2013"
""

which is correct albeit not what you might want.
