tm:SuBject is treated like tm:subject

[GoogleCodeExporter]

The query //tm:SuBjEcT returns the same results as //tm:subject or 
//Tm:subject. That's wrong. 

The prefix part and local part of a QName are case-sensitive. If you expand a 
QName, you get an IRI and if you treat QNames case-insensitive, these IRIs 
would be equal, too:

<http://psi.example.org/SUBJECT> 
<http://psi.example.org/Subject> 
<http://psi.example.org/SubJeCt>
