The validation is no longer built in in the Xerces 2 parser [1]. The
parser pipeline may consist of any combinations of components. The
components, such as XML Schema Validator, can be removed or added to the
pipeline. Moreover, using XNI [2] users can write new components and add
those to the pipeline (using new parser configurations). 
For more information refer to XNI design [3].
