This part of ISO 10303 formally specifies the XML representation by specifyingan overall XML schema for the exchange document and additional XML schemas that correspond tothe EXPRESS schemas that govern the exchange data sets.The following are within the scope of this part of ISO 10303:— specification of the form of XML documents containing EXPRESS schemas and data governed byEXPRESS schemas (see Clause 5);— for an arbitrary EXPRESS schema, specification of an XML schema that corresponds to theEXPRESS schema and formally describes the XML representation of data governed by that schema(see Clause 6);— specification of the representation of values of EXPRESS data types as XML element content andas XML attribute values (see Clause 9);— specification of the set of configuration directives that may be used to specify options for thestructure of the XML representation of data sets that conform to EXPRESS schemas (see Clause 10).The following are outside the scope of this part of ISO 10303:— specification of XML Schema declarations or definitions that depend on the semantic intent, asdistinct from the EXPRESS language statements, of any particular EXPRESS schema;— specification of mappings from the XML Schema language to the EXPRESS language;— specification of the mapping to an EXPRESS schema from an XML schema that has been derivedfrom an EXPRESS schema.
