     // JAXB converts an XML Schema into Java classes.  Version 1.3.1 of
     // COLLADASchema.xsd introduced a conflict for JAXB in that there are
     // two "source" elements under "mesh".  This JAXB customization file
     // resolves the problem by naming the first one "source1" and the
     // second "source2" so that the data can be accessed via the methods
     // "getSource1()" and "getSource2()", respectively.
     //
