// (which means that path1 had no parent element).
// Because of that rectangle's color on the page effectively turns to green
path2->set_Fill(doc->CreateSolidColorBrush(System::Drawing::Color::get_Green()));

// Now add path2 once again. Now path2 has parent. So path3 won't be the same as path2.

path7->get_RenderTransform()->Translate(0.0f, 300.0f);
// ... and set opacity for path7
path7->get_Fill()->set_Opacity(0.8f);
// Now opacity effects independantly as soon as property values are cloned along with the element

// The following code block is equivalent to the previous one.
// Add path6 itself. path6 and path7 are not the same. Although their Fill property values are the same 
//XpsPath path7 = doc.Add(path6);
//path7.RenderTransform = path7.RenderTransform.Clone();
//path7.RenderTransform.Translate(0, 300);
// To "disconnect" path7's Fill property from path6's Fill property reassign it to its clone (or path6's Fill clone)
//path7.Fill = ((XpsSolidColorBrush)path7.Fill).Clone();
//path7.Fill.Opacity = 0.8f;
