Runs events through a javax.xml.validation.ValidatorHandler and performs validation/infoset-augmentation by an external validator.

This component sets up the pipeline as follows: 

            __                                           __
           /  |==> XNI2SAX --> Validator --> SAX2XNI ==>|  
          /   |                                         |   
      ==>| Tee|                                         | next
          \   |                                         |  component
           \  |============other XNI events============>|  
            ~~                                           ~~

only those events that need to go through Validator will go the 1st route, and other events go the 2nd direct route.
