/**
* This class is the implementation of BindingComponent from an XML Schema point
* of view. This specific implementation wraps an XML Schema annotated
* structure.
* <p>
* The XML Schema structure can be only of four different types:
* <ul>
* <li>Element: it represents an XML Schema element.</li>
* <li>ComplexType: it represents an XML Schema complexType.</li>
* <li>ModelGroup: it represents an XML Schema Model group definition.</li>
* <li>Group: it represents an XML Schema Model Group.</li>
* </ul>
* <p>
* The three first items can be customized using a binding file. Thus the
* XMLBindingComponent class takes into account the presence or not of a custom
* binding document in the computation of the needed information for the Source
* Generator to generate java classes from an XML Schema.
* <p>
* The customizable items are detailled in the binding file documentation.
* <p>
* This class acts like a <i>window</i> on a particular XML Schema structure
* that the user controls by changing the view on the Annotated Structure he is
* interested in.
* <p>
