An XML Schema processor with preliminary support for the W3C XML Schema 1.1 Recommendation (in two parts). This artifact was sourced from the xml-schema-1.1-dev branch (r1667115) and built using JDK 7. The org.apache.xerces and org.eclipse.wst packages are relocated to avoid conflicts with other components that depend on the latest public Xerces release (2.11.0).
The newest version!
