Schema, Parsers, validators - Java
An XML schema is a description of a type of XML document, typically expressed in terms of constraints on the structure and content of documents of that type, above and beyond the basic syntax constraints imposed by XML itself. An XML schema provides a view of the document type at a relatively high level of abstraction.

CyberNeko RelaxNG Validator
ManekiNeko is a parser configuration that allows users to validate documents using Relax NG grammars and access the document information using standard programming interfaces. The parser configuration does not implement a Relax NG validator, however. Instead, it wraps James Clark's Jing validator to validate documents using a Relax NG grammar.
