xscs brings some of the benefits of the Relax NG compact syntax approach to XSD. I.e. don't tie yourself up in purist knots by describing your grammar in the same syntax as the instances it describes. (A good rule of thumb, I've come to believe.).
It cannot do anything about the often heinious semantic complexity of XSD but its a help at the first-pass-grok level.
