I'm a final year computer science and engineering undergraduate of University of Moratuwa. I'm interested in working on ticket "XALANJ-2550 - Complete support for StAXSource / StAXResult"  in GSoC 2013.
I went through the resources provided by Michael in one of his comments  to get familiar with StAX, JAXP and XSLT. However looking at the XALAN source I could not clearly understand where I should start with. Can someone help me giving a starting point so that I can start working on it?
