Merging selected Xerces 2.11.0 updates into JAXP [JEP 255]

Xerces is a library used for parsing XML in Java. It was updated to 2.11.0 in late 2010, so JEP 255's aim was to update JAXP to incorporate changes in Xerces 2.11.0.

Prior to Java 9, the JDK's latest update regarding XML processing was based on Xerces 2.7.1. There were some additional changes to JDK 7 based on Xerces, 2.10.0. JEP 255 is a further refinement of the JAXP based on Xerces 2.11.0.
