Hi Ishan, Welcome to the mailing list and thanks for considering Xerces for GSoC this year.
Your interest in this project is very timely. The specification just reached Candidate Recommendation [1] last month with the W3C inviting [2] the community to start implementing it. A SCD parser and evaluator will make it easier for users to navigate an XSModel, dramatically reducing the amount of code they need to write to retrieve specific schema components. Though somewhat different from this project you might find some inspiration from the XPath 2.0 support [3][4] that was implemented for XML Schema 1.1. I believe Hiranya used JavaCC [5] to generate the XPath parser and think that might also work for SCD so would be worth having a look at this tool. For the evaluator you're going to need to have a good understanding of the XML Schema API [6] and how to navigate an XSModel. There are samples around which show how to use it. The one [7] that Mukul has been writing lately might be educational for you. Thanks again for you interest and looking forward to hearing more about your proposal.
