Translation and localization attributes
DITA elements have several attributes that support localization and
         translation.
      
      - @xml:lang
 - Identifies the language of the content, using the standard language and country codes. For instance, French Canadian is identified by the value fr-CA. The @xml:lang attribute asserts that all content and attribute values within the element bearing the attribute are in the specified language, except for contained elements that declare a different language.
 - @translate
 - Determines whether the element requires translation. A default value can often be inferred from the element type. For example, <apiname> might be untranslated by default, whereas <p> might be translated by default.
 - @dir
 - Determines the direction in which the content should be rendered.
