>I had several SQL computer science courses but "emptiable" doesn't sound familiar to me. "Outer" is a good word. It is also similar to most JOIN terminology for SQL languages.

Perhaps you misread my point: I was suggesting that the concept of "outer
join", and its relationship to the semantics of FLOWR expressions, would only
be understood by those with an advanced computer science education, whereas
"emptiable" might be more accessible/memorable to the masses.
