Internal Program Version: xerces-j2  2.12.2

Xerces2 is an XML parser in the Apache Xerces family. This version is the
reference implementation of the Xerces Native Interface (XNI), a modular
framework for building parser components and configurations.

Xerces2 implements the Document Object Model Level 3 Core and Load/Save W3C
Recommendations, the XML Inclusions (XInclude) W3C Recommendation, and supports
OASIS XML Catalogs v1.1. It can parse documents conforming to the XML 1.1
Recommendation, except that it does not yet provide an option to enable
normalization checking as described in section 2.13 of this specification. It
handles name spaces according to the XML Namespaces 1.1 Recommendation, and
serializes XML 1.1 documents if the DOM level 3 load/save APIs are in use.
