信息技术——文档模式定义语言(DSDL)第4部分:基于名称空间的验证调度语言(NVDL)
ISO/IEC 19757-4:2006 specifies a Namespace-based Validation Dispatching Language (NVDL). An NVDL script controls the dispatching of elements or attributes in a given XML document to different validators, depending on the namespaces of the elements or attributes. An NVDL script also specifies which schemas are used by these validators. These schemas may be written in any schema languages, including those specified by ISO/IEC 19757.
