text-direction

<xs:simpleType name="text-direction">
  <xs:annotation>
    <xs:documentation>The text-direction type is used to adjust and override the Unicode bidirectional text algorithm, similar to the W3C Internationalization Tag Set recommendation. Values are ltr (left-to-right embed), rtl (right-to-left embed), lro (left-to-right bidi-override), and rlo (right-to-left bidi-override). The default value is ltr. This type is typically used by applications that store text in left-to-right visual order rather than logical order. Such applications can use the lro value to better communicate with other applications that more fully support bidirectional text.</xs:documentation>
