Path markup syntax for PathGeometry - silverlight

Question

Using path markup syntax, you can easily create Paths with custom shapes like a diamond:
<Path Data="M 0,5 L 5,0 L 10,5 L 5,10 Z" />
Is it possible to use this syntax in a PathGeometry? Per the link above (which is for WPF and not Silverlight), I tried using PathGeometry.Figures:
<local:SomeControl>
<local:SomeControl.Geometry>
<PathGeometry Figures="M 0,5 L 5,0 L 10,5 L 5,10 Z" />
</local:SomeControl.Geometry>
</local:SomeControl>
but this throws a XamlParseException
failed to create a 'PathGeometry.Figures' from the text 'M 0,5 L 5,0 L 10,5 L 5,10 Z'
Do I really need to use the extended form below, or is there some way to use the short string?
<PathGeometry>
<PathFigure StartPoint="0,5" IsClosed="True" IsFilled="True">
<LineSegment Point="5,0" />
<LineSegment Point="10,5" />
<LineSegment Point="5,10" />
</PathFigure>
</PathGeometry>

I just noticed that the Blend SDK has a ConvertToPathGeometry helper method. So it would be easy to create an IValueConverter using this:
return GeometryHelper.ConvertToPathGeometry((string)parameter);
And then the Geometry could be set to a PathGeometry instance like this:
<local:SomeControl Geometry="{Binding ConverterParameter='M 0,5 L 5,0 L 10,5 L 5,10 Z',
Converter={StaticResource PathGeometryConverter}}"
/>
