This is what Heidegger calls thrownness Geworfenheita having-been-thrown into the world. It's a design pattern that's useful in every programming language, and as we'll see shortly, it's also pretty darn useful as a general-purpose persistence strategy.

The choice group is followed by the comment and items element declarations, and both the choice group and the element declarations are children of a sequence group.

Researchers have focused almost exclusively on generating distinctive referring expressions, that is, referring expressions that uniquely identify their intended referent.
