Regular Language for XML Next Generation RelaxNG (REgular LAnguage for XML Next Generation) est un langage de schéma XML. -
RelaxNG est une alternative aux DTD et à W3C XML Schema, qui combine les avantages de ces deux autres langages. -
RelaxNG est un standard OASIS et une norme ISO/CEI. -
Deux syntaxes : une syntaxe XML (alternative à W3C Schema) et une syntaxe compacte (alternative aux DTD). -
RelaxNG ne définit que la structure (comme les DTD) et utilise W3C XML Schema pour le typage des données. http://relaxng.org/

Les XML Schema ont été proposés par le W3C pour permettre de dépasser les limites des DTD. http://www.w3.org/XML/Schema On notera en particulier : -
une syntaxe XML -
l'extension de l'expression des règles d'organisation structurelle (héritage, réutilisation, etc.) -
l'ajout d'un langage de typage des éléments (particulièrement utile pour les format XML orientés données)
