/**
    A CIMQualifier represents a DMTF standard CIM qualifier.
    A CIMQualifier differs from a CIMQualifierDecl in that it has no scope
    attribute.

    <p>The CIMQualifier class uses a shared representation model, such that
    multiple CIMQualifier objects may refer to the same data copy.  Assignment
    and copy operators create new references to the same data, not distinct
    copies.  An update to a CIMQualifier object affects all the CIMQualifier
    objects that refer to the same data copy.  The data remains valid until
    all the CIMQualifier objects that refer to it are destructed.  A separate
    copy of the data may be created using the clone method.
