Hi all,
   The Apache Xerces project team is pleased to announce that version
2.12.1 of Apache Xerces-J is now available.

Xerces-J 2.12.1 can be downloaded at: http://xerces.apache.org/mirrors.cgi.

This release is a bug fix release. It fixes few bugs which were present in
Xerces-J 2.12.0 and also includes a few other minor enhancements.

Specifically, the changes introduced in this release are:

* Implemented few fixes for XML Schema identity constraints, within
Xerces's XML Schema 1.0 and 1.1 validators. [Sandy Gao, Mukul Gandhi]

* When XML Schema 1.1 validations are done, where xs:assert are contained
within xs:override, the XPath expressions within xs:assert can't see XML
namespace bindings specified at certain locations in schema documents. This
release fixes this. [Mukul Gandhi, Patrick Gratz]

* When XML Schema 1.1 validations are done, when the schema document is
specified via xsi:schemaLocation attribute in the XML document, when full
XPath 2.0 is used with CTA, for certain use cases validation was not
occurring correctly. This release fixes this. [Mukul Gandhi, Yitzhak
Khabinsky]

* For certain cases, while doing XML Schema 1.1 xs:assert validations,
error messages appeared like following 'FOAR0001 - Division by zero'.
Modified such error messages, to now contain the character ':' instead of
'-' (since, the character '-' can be confused with a negation symbol).
[Mukul Gandhi]

* The 'XML Schema 1.1 structures' REC in the section, "3.2.3 Constraints on
XML Representations of Attribute Declarations (Schema Representation
Constraint: Attribute Declaration Representation)" mentions, '5 If fixed
and use are both present, use must not have the actual value prohibited'.
This functionality is newly introduced in XML Schema 1.1. Fixed a runtime
validation issue for this XSD clause, when XSD 1.1 implementation is
invoked in XSD 1.0 mode. [Mukul Gandhi]

* Xerces-J was previously not building from sources when Java 9+ was used.
This release fixes this. [Mukul Gandhi, Michael Glavassevich, Thomas Pasch]

* XML Schema 1.1 has introduced the attribute 'ref' on xs:key, xs:unique
and xs:keyref. When certain such schema documents were processed by
Xerces-J's XSD 1.1 implementation in XSD 1.0 mode, a
java.lang.NullPointerException was displayed to the user when the schema
document is processed with Xerces sample jaxp.SourceValidator. This release
fixes this. [Michael Glavassevich, Mukul Gandhi]

* Fixed minor bugs and made various improvements. [Michael Glavassevich,
Mukul Gandhi, Octavian Nadolu]

* Added many new tests to the regression since the previous Xerces release,
for Xerces's XML Schema 1.0 and 1.1 implementations. [Mukul Gandhi]
