Degree of Binary Literature

Question: Can a work contain literary element but not be literature?

Yes, I think that many works could. Any instruction manual satisfies the first two necessary conditions (mentioned in the previous post), however, it doesn't satisfy the last, or any of the sufficient. Additionally, a history textbook could satisfy all the necessary but none of the sufficient. A speech or play without being written down can satisfy all of the sufficient conditions and but not the first necessary one.

I think it is also important to have literature on a sliding scale, though I think there is a line where something is or is not literature. Something could very well be very close to literature, satisfying all necessary but only one sufficient. Additionally, there would be little doubt that a work that satisfies all the necessary conditions and the sufficient definitions is literature.
