SyncroSoft has released oNVDL, an open source NVDL implementation based on James Clark's Jing. "NVDL stands for Namespace-based Validation Dispatching Language and it is Part 4 of ISO/IEC 19757 DSDL (Document Schema Definition Languages). It allows specifying sections of XML documents to be validated against different schemas thus enabling the creation of complex documents containing multiple languages without the need to modify the schemas that define each language to take into account the other languages. It allows also mixing different schema types like XML Schema, Relax NG and Schematron. A typical example is a document that contains XForms content inside XHTML."
SyncroSoft has also released <Oxygen/> 8.0, $298 payware XML editor written in Java . Oxygen supports XML, XSL, DTDs, XQuery, SVG, Relax NG, Schematron, and the W3C XML Schema Language. Version 8.0 adds a grid editor, an XML database perspective, and various other small improvements.
