Internationalization Tag Set

Problem: Different XML formats use different solutions for I18N issues (unfortunately, the most widespread approach is to not do anything)

Solution: Tag set for Internationalization/Localization

Tag examples:

• <span> for internationalization attributes such as xml:lang
• <ruby>
• attributes for bidirectional embedding/override (for Arabic/Hebrew)
• tag for unencoded characters
• tag for glyph variants
• translatability flag
• notes to translators
