==== Scope ====
  : //This International Standard supports the Meta-Object Facility (MOF) Core defined in ISO/IEC 19508. MOF is the foundation technology for describing metamodels. It covers a wide range of domains and is based on a constrained subset of UML. XML Metadata Interchange (XM I) is a widely used XML interchange format. It defines the following aspects involved in describing objects in XML://
    * //The representation of objects in terms of XML elements and attributes.//
    * The standard mechanisms to link objects within the same file or across files.//
    * The validation of XMI documents using XML Schemas.//
    * Object identity, which allows objects to be referenced from other objects in terms of IDs and UUIDs.//

  : // XMI describes solutions to the above issues by specifying EBNF production rules to create XML documents and Schemas that share objects consistently.//
