This class adds the functionality of namespace processing.
This class has been modified as per the new design which is more suited to
efficiently build pull parser. Lot of improvements have been done and
the code has been added to support stax functionality/features.
This class scans an XML document, checks if document has a DTD, and if
DTD is not found the scanner will remove the DTD Validator from the pipeline and perform
namespace binding.
