I want to know the answer to the following question:
During which dynasty was the term Xizang first used?
All the background I'm provided with is that "Tibetan people, language, and culture, regardless of where they are from, are referred to as Zang (Chinese: 藏; pinyin: Zàng) although the geographical term Xīzàng is often limited to the Tibet Autonomous Region.". Is that enough to answer the question?
