XML结构完整性约束(XSICs)描述了XML文档中节点或路径之间结构关系,这种约束可以看成是DTDs的扩展和补充.定义了元素排他性包含、必需性包含、路径蕴含、路径同现和路径互斥五种XSICs的语法和语义,研究了如何使用XSICs扩展DTDs,并解决了有DTDs的情况下结构完整性约束的逻辑蕴含问题和一致性问题.

Structural integrity constraints for XML(XSICs) specify structural relationships between different nodes and paths in XML documents, which can be regarded as an extension of DTDs. The paper defines the syntax and semantics of XSICs,including element exclusive inclusion,obligatory inclusion,path implication,path co-occurrence and path mutual-exclusion,studies bow to extend DTDs with XSICs,and resolves their logical implication and consistency problems in the presence of DTDs.
