If you have read this article (“Ācāriya Buddhaghosa and Master Yinshun 印順 on the Three-aṅga Structure of Early Buddhist Texts”) by Choong Mun-keat regarding the issue of the three angas, please do tell us your views about Buddhaghosa and Yinshun on the EBTs.
I consider Buddhaghosa just wanted to promote his Pali tradition, i.e., the Pali Pitakas are the words/language of the Buddha, and also originated from the first council.
Analayo seems to ignore completely the relevant findings of Yinshun when he discusses about the angas in his articles. It will be useful if he could directly review the findings of Yinshun. Possibly, Analayo is unable to read the Chinese writings by Yinshun. Based mainly on the Pali information, he considers the angas are not the particular works in the Pali texts or EBTs.
