/**
 * This interface extends the simple XMLStreamReader interface adding
 * methods to get java objects asociated with schemas simple types like:
 * ints, long, BigIntegers, Dates etc
 *
 * Note: Given the fact that an implemetation of this interface will not
 * run validation in the stream, we will not include support for lists,
 * enumeration and unions. They might be possible to introduce but the
 * user has to push the corect schema type. Because usualy the backends
 * are not list/union aware, there would be not performance win from this.
 * If interest rises for this, support should be added.
