20//! Some fields of an IGES entity may be
21//! - Undefined
22//! - Defined as a single item
23//! - Defined as a list of items.
24//! A typical example, which presents this kind of variation,
25//! is a level number.
26//! This enumeration allows you to identify which of the above is the case.
27//! The semantics of the terms is as follows:
28//! - DefNone indicates that the list is empty (there is not
29//! even a single item).
30//! - DefOne indicates that the list contains a single item.
31//! - DefSeveral indicates that the list contains several items.
32//! - ErrorOne indicates that the list contains one item, but
33//! that this item is incorrect
34//! - ErrorSeveral indicates that the list contains several
35//! items, but that at least one of them is incorrect.
