Why is PolyPolygonShape excluded from DML export?

[Regina Henschel]

Hi all,

this is about export ODF shape -> OOXML.

bool DocxSdrExport::Impl::isSupportedDMLShape(const 
uno::Reference<drawing::XShape>& xShape)
{
     uno::Reference<lang::XServiceInfo> xServiceInfo(xShape, 
uno::UNO_QUERY_THROW);
     if 
(xServiceInfo->supportsService("com.sun.star.drawing.PolyPolygonShape")
         || 
xServiceInfo->supportsService("com.sun.star.drawing.PolyLineShape"))
         return false;

excludes SdrPathObj objects from DML export, in case they have no 
control points. I see no reason, why a simple polygon is excluded, but a 
bezier curve is allowed.

Effect is, that it is only exported as VML and so looses e.g. line 
transparency.

Is it possible, that the exclusion was only forgotten to remove, or is 
there a valid reason?

Kind regards
Regina
