z/OS® XML supports the parsing of Extensible Dynamic Binary XML (XDBX) streams with validation. This allows a caller to pass binary XML streams, which are more compact and which can be processed by the validating parser using fewer resources. The result is a conventional z/OS XML record stream. See http://www.ibm.com/support/docview.wss?&uid=swg27019354 for more information on the XDBX binary XML format.
