Hi all,

I've been playing around with advanced stylization for the past while, but
still have a number of layers in the simple (point, line, polygon, text)
format.

I have some custom styled point features that I would like to have drawn
entirely due to layer order rather than allowing label text to float on top
of it.

Is there a way I can achieve this?  RenderingPass (from RFC29) looked
promising, but only appears to work for the current layer.

Layer Definition snippet:

<CompositeTypeStyle>
  <CompositeRule>
    <LegendLabel />
    <CompositeSymbolization>
    <SymbolInstance>

 <ResourceId>Library://Nanaimo/Shared/Symbols/POI/Fire.SymbolDefinition</ResourceId>
      <ParameterOverrides />
      <AddToExclusionRegion>true</AddToExclusionRegion>
    </SymbolInstance>
    </CompositeSymbolization>
  </CompositeRule>
</CompositeTypeStyle>

Symbol Definition snippet:

<Graphics>
  <Image>
    <ResizeControl>'ResizeNone'</ResizeControl>
    <Reference>
    <ResourceId/>
    <LibraryItemName>'fire.png'</LibraryItemName>
    </Reference>
    <SizeX>8.0</SizeX>
    <SizeY>9.0</SizeY>
    <SizeScalable>True</SizeScalable>
    <Angle>0.0</Angle>
    <PositionX>0.0</PositionX>
    <PositionY>4.0</PositionY>
  </Image>
  <Path>
    <Geometry>M -1.0,0.0 L 0.0,1.0 L 1.0,0.0 L 0.0,-1.0 Z</Geometry>
    <FillColor>ff008800</FillColor>
  </Path>
</Graphics>

Thanks!
Jason
