I want to know the answer to the following question:
Mahayana schools recognize all or part of what?
All the background I'm provided with is that "Some of these sutras became for Mahayanists a manifestation of the Buddha himself, and faith in and veneration of those texts are stated in some sutras (e.g. the Lotus Sutra and the Mahaparinirvana Sutra) to lay the foundations for the later attainment of Buddhahood itself.". Is that enough to answer the question?
Answer: no
