This directory contains version 20090818 of Jing, a validator for RELAX NG and other schema languages.

The directory `bin` contains `jing.jar`, which contains the code for Jing, ready to use with a Java runtime. For more information on how to use Jing, see this document.

Apart from `jing.jar`, the `bin` directory contains some third-party jar files, which are used for XML parsing (under a pre-1.4 JRE that does not provide the Java XML parsing extension) and for validating with schema languages other than RELAX NG:

`saxon.jar`
  Comes from the Saxon 6.5.5 distribution. Used for Schematron 1.5 validation.
`xercesImpl.jar`
`xml-apis.jar`
  Come from the Xerces2 Java 2.9.1 distribution. Used for W3C XML Schema validation and for XML parsing. Xerces2 Java is under the Apache License Version 2.0, which requires the following notice:
