RELAX NG - Wikipedia, the free encyclopedia
In computing, RELAX NG (REgular LAnguage for XML Next Generation) is a schema language for XML, based on Murata Makoto’s RELAX and James Clark’s TREX. A RELAX NG schema specifies a pattern for the structure and content of an XML document. A RELAX NG schema is itself an XML document; however, RELAX NG also offers a popular compact, non-XML syntax.[1] Compared to other popular schema languages, RELAX NG is relatively simple. It is defined by a committee specification of the OASIS RELAX NG technical committee, and also by part two of the international standard ISO/IEC 19757: Document Schema Definition Languages (DSDL).[2][3]
