/*
* ENUM: SE_Multiplicity

* This data type specifies the multiplicities allowed for
* defined between classes, and is used by SE_Requirement. These
* multiplicities relate directly to the multiplicity symbols

* See the examples for SE_Requirement for more details.

Enumerant Notes
Exactly one instance of the target class shall participate
in the relationship.
At most one instance of the target class shall participate
in the relationship; it is possible that none shall be present.
While it is possible that no instances of the target class
may be present, any number of instances are permitted.
At least one instance of the target class shall participate
in the relationship, but more than one may be present.
Exactly N instances of the target class shall be present,
where N is a number specified by the given SE_Requirement.
At least N instances of the target class shall be present,
and no more than M instances, where N and M are numbers
specified by the given SE_Requirement.
At least N instances of the target class shall be present,
where N is a number specified by the given SE_Requirement.
However, there is no upper bound on the number of instances
of the target class that may be present.
Prev: SE_Month.
