The ITS Working Group is aiming to produce a set of tags that people can use to ensure both internationalization and localizability in their schemas - be they based on DTDs, XML Schema or other technologies. Here we will give some examples of the kind of requirements we are currently developing.

The top line on the slide shows some text with an embedded Hebrew quotation (saying "Internationalization Activity, W3C"). In Hebrew, the W3C should appear to the left of the Hebrew text. However, the Unicode bidirectional algorithm will place 'W3C' to the right of the Hebrew. Some additional markup is needed to create an embedded directional level so that the bidirectional algorithm can produce the desired effect. In XHTML this would be the attribute dir with value set to rtl. Provision of such markup falls within the scope of the ITS work, and addresses international use of the schema in question.
