Scope

This part of ISO/IEC 19757 specifies RELAXING, a schema language for XML. A RELAXING 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/IEC 19757 establishes requirements for RELAXING schemas and specifies when an XML document matches the pattern specified by a RELAXING schema.
