167 : * queryable via @see SfxItemPool::GetMetric(sal_uInt16) const (and not

174 : * @return SfxItemPresentation SFX_ITEM_PRESENTATION_NAMELESS

186 : * pSvxFontItem->GetPresentation( SFX_PRESENTATION_NAMELESS, ... )
187 : * "12pt" with return SFX_ITEM_PRESENTATION_NAMELESS
188 : *
189 : * pSvxColorItem->GetPresentation( SFX_PRESENTATION_COMPLETE, ... )
190 : * "red" with return SFX_ITEM_PRESENTATION_NAMELESS
191 : * Because the SvxColorItem does not know which color it represents
192 : * it cannot provide a name, which is communicated by the return value
193 : *
194 : * pSvxBorderItem->GetPresentation( SFX_PRESENTATION_COMPLETE, ... )
