Yes they are all the same, so I guess I'm saying that it feels a little 
strange to have:

   createLiteral(100, "xsd:double").equals( createLiteral(+1e2, 
"xsd:double") ) === TRUE

whilst if the original source was say turtle, then they would not be 
considered equal, seems like unexpected functionality to me.

Back to reality, just what do we write in the RDF API specification?

- keep it as is, which appears to work, afaict - compare value if you 
know the datatype, else compare lexical form

- change to read something like "equality is defined by RDF <link> here"

- something else?
