The MSDN documentation is incorrect. In the current released version of Silverlight 2, 2.0.31005.0, you cannot use attribute syntax for the Figures property of a PathGeometry in XAML. For instance, the following will fail, throwing a XamlParseException.

<Path Fill="Black">

<Path.Data>

<PathGeometry Figures="M0,0L9,0 9,9 0,9Z" />

</Path.Data>

</Path>

This is true for path geometries used in clipping regions as well. The following will fail in the same way.

<Rectangle Width="23" Height="23" Fill="Black">

<Rectangle.Clip>

<PathGeometry Figures="M0,0L9,0 9,9 0,9Z" />

</Rectangle.Clip>

</Rectangle>

Instead, you must use the more verbose element syntax.

<Rectangle Width="23" Height="23" Fill="Black">
<Rectangle.Clip>
<PathGeometry>
<PathGeometry.Figures>
<PathFigure StartPoint="0,0" IsClosed="True">
<LineSegment Point="9,0" />
<LineSegment Point="9,9" />
<LineSegment Point="0,9" />
</PathFigure>
</PathGeometry.Figures>
</PathGeometry>
</Rectangle.Clip>
</Rectangle>

This is not true for the Data property of a Path. The following will work as expected.

<Path Fill="Black" Data="M0,0L9,0 9,9 0,9Z" />
