XAML export not compatible with Silverlight

Originally reported in http://stackoverflow.com/questions/11331549/why-does-this-xaml-path-crash-silverlight

The following Xaml path works fine in WPF but crashes in Silverlight. I can verify this behaviour in Kaxaml.

The path code is

<Path Fill="#FFEDEDED" StrokeThickness="1" Stroke="#FFA3A3A3" Opacity="0.7"
                VerticalAlignment="Center" HorizontalAlignment="Center" >
    <Path.Data>
        <PathGeometry Figures="m 1 2 l 4.0525 5.2361 l 4.0527 -5.2361 z "/>
    </Path.Data>
</Path>

The exception is a script error

    Unhandled error in Silverlight Application. Failed to create a System.Windows.Media.PathFigureCollection from the text 'm 1 2 l 4.0525 5.2361 l 4.0527 -5.2361 z'

Its supposed to draw a triangle.

Unlike WPF Silverlight does not support converting a string to Figures.

The equivalent triangle, authored via Blend, for Silverlight is:

<Path Fill="#FFEDEDED" StrokeThickness="1" Stroke="#FFA3A3A3" Opacity="0.7"
                VerticalAlignment="Center" HorizontalAlignment="Center"
                Data="m 1 2 l 4.0525 5.2361 l 4.0527 -5.2361 z" />
