Document Schema Definition Languages
Document Schema Definition Languages ( DSDL ) is an ongoing ISO project to standardize various methods for checking XML documents. The combination of different methods allows a more complete validation of documents than would be possible with just one technique and goes beyond comparable W3C procedures .
DSDL is specified in the ISO / IEC 19757 standard.
