XAML - Convert SVG to XAML and use as a resource on a button

I wanted to use some nice icons in SVG format in Silverlight.
Silverlight doesn't support SVG though.
So I found a tool that can convert them to XAML.
It's a command line tool that can be used as follows:

svg2xaml D:\Projects\ArrowUp.svg

To make it valid I had to tweak the result a bit.
One thing was to remove the PathGeometry's and put their data directly in the Path's.
Then I surrounded it with:

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

                   xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

                   xmlns:toolkit="clr-namespace:System.Windows.Controls;

                                  assembly=System.Windows.Controls.Toolkit">

  <Style x:Key="ArrowUp" TargetType="Button">

    <Setter Property="Template">

      <Setter.Value>

        <ControlTemplate TargetType="Button">

          <toolkit:Viewbox Stretch="Uniform">

            <!-- The XAML -->
          </toolkit:Viewbox>

        </ControlTemplate>

      </Setter.Value>

    </Setter>

  </Style>

</ResourceDictionary>

put it's build action to "Content" and included it with:

<this:frmBase.Resources>

  <ResourceDictionary>

    <ResourceDictionary.MergedDictionaries>

      <ResourceDictionary Source="Images/ArrowDown.xaml" />

    </ResourceDictionary.MergedDictionaries>

  </ResourceDictionary>

</this:frmBase.Resources>

Then I used the resource as follows:

<Button Style="{StaticResource MenuButton}">

  <Button.Content>

    <Button Style="{StaticResource ArrowDown}" Click="Button_Click" />

  </Button.Content>

</Button>

where "MenuButton" is another global style resource with a custom template containing a ContentPresenter.
