  In a broad sense, a Schema Language is a formal language which is used to describe the properties of "information". As an example, RDF Schema is a language for describing properties of all kinds of information resources. In a narrow sense, and this defines the scope of the ITS Working Group, a Schema Language describes the properties of a specific resource, i.e. markup. ITS deals with documents which consist of textual data and XML markup, e.g. elements, attributes etc. Three Schema Languages which have been developed for XML are of interest for ITS purposes: XML-DTDs, XML Schema and RELAX NG. These can be used for describing vocabularies for documents, i.e. a set of names for elements and attributes. The ITS Working Group is not concerned with Schema Languages like Schematron, which does not describe a vocabulary, but rather a part of a given document.

+ XML instances which leave the production environment sometimes differ from the corresponding XML instances which reside inside the production environment. A content management system for production purposes for example may store XML instances in a format which is not valid DocBook. Valid DocBook will only be generated for deployment purposes. Source-as-deliverable XML instances do not differ.
