  Bibliography

Describes RELAX NG, a schema language for XML.

This part of ISO/IEC19757 specifies RELAX NG, a schema language for XML. A RELAX NG schema specifies a pattern for the structure and content of an XML document. The pattern is specified by using a regular tree grammar. This part of ISO/IEC19757 establishes requirements for RELAX NG schemas and specifies when an XML document matches the pattern specified by a RELAX NG schema.
