 * queryable via @see SfxItemPool::GetMetric(sal_uInt16) const (and not
 * via the SfxPoolItem instance or subclass, the own unit of measure is
 * passed to 'eCoreMetric'.
 *
 * The corresponding unit of measure is passed as 'ePresentationMetric'.
 *
 *
 * @return SfxItemPresentation     SfxItemPresentation::Nameless
 *                                 A textual representation (if applicable
 *                                 with a unit of measure) could be created,
 *                                 but it doesn't contain any semantic meaning
