Interface: TextLanguage

The span's language tags (w:lang / a:rPr@lang + @altLang) — BCP-47 tags such as "en-US" or "ja-JP", one per script slot.

The slots parallel the typeface / script-category triple: docx's val / eastAsia / bidi and pptx's lang / altLang fold onto latin / east_asian / complex. Each is independently optional — a span may tag only its East Asian text.

Properties
