@juherr - If you find some time please help let me know your thoughts on the two questions i posted. Post which I think we can get this PR merged.

[juherr]

@krmahadevan sure. But I don't see them. Did you finish the review?

My bad. Forgot that. Now I finished it.

@krmahadevan Please check the description again before merging. If you want to check XML samples, just add one suite file into the testng-core/src/test/resources/samples/xsd folder and my tests will check its validity. If you think the XML is wrong and the test keep to be green, it will mean that the schema is not good enough =)
