libxerces2-java 2.11.0-8 (amd64 binary) in ubuntu bionic

 The Xerces2 Java parser is the reference implementation of XNI, the
 Xerces Native Interface, and also a fully conforming XML Schema processor.
 .
 Xerces2-J supports the following standards and APIs:
  * eXtensible Markup Language (XML) 1.0 Second Edition Recommendation
  * Namespaces in XML Recommendation
  * Document Object Model (DOM) Level 2 Core, Events, and Traversal and
    Range Recommendations
  * Simple API for XML (SAX) 2.0.1 Core and Extension
  * Java APIs for XML Processing (JAXP) 1.2.01
  * XML Schema 1.0 Structures and Datatypes Recommendations
  * Experimental implementation of the Document Object Model (DOM) Level 3
    Core and Load/Save Working Drafts
  * Provides a partial implementation of the XML Inclusions (XInclude) W3C
    Candidate Recommendation
 .
 Xerces is now able to parse documents written according to the XML 1.1
 Candidate Recommendation, except that it does not yet provide an option to
 enable normalization checking as described in section 2.13 of this
 specification. It also handles namespaces according to the XML Namespaces 1.1
 Candidate Recommendation, and will correctly serialize XML 1.1 documents if
 the DOM level 3 load/save API's are in use.
