When composites are compared in boolean
expressions, the corresponding components of the composite are
compared. For the composite comparison to be true, the comparison
between the corresponding components must be true for all
components of the composites. Otherwise, the comparison will return
a value of false.

For example, these two composites are compared to
determine whether they are equal.

AB-349

AB-375

The composites contain two components, so two
comparisons are made: AB = AB and 349 = 375.
The first comparison is true, but the second is not, so false is
returned for the entire comparison.
