I am new to Paxtools and am going through the Paxtools Developer documentation. In practicing with Paxtools java library I have come across a couple issues. Any help/advice would be appreciated.

1.) I get an undefined method error when using getRDFId() on a BioPAXElement object. Other methods from the BioPAXElement interface work fine though.

2.) Is there a way to setURI of a BioPAXElement without using the model.addNew() method? How else can I make a BioPAXElement with a URI, but not add it to any particular model. I see that there is a private setURI() method in the BioPAXElementImpl class. Any thoughts?
