Greetings,

I know this is an issue that has been addressed before, but we are having some 
issues and am hoping for guidance.

We have a point layer that has, in at least one instance, two points at the 
exact some location. Optimally, if would be best if both symbols rendered in a 
"stacked" fashion. However, only one of the features is showing. The next best 
option would be to prioritize the point drawn based on attribute value. We have 
used the <FeatureTypeStyle> tag, but the rendering is still not placing 
priority as we have indicated. I have a snippet of the SLD below.

Any suggestions would be greatly appreciated.

<FeatureTypeStyle>
        <Rule>
          <Name>Type 1</Name>
          <Title>Type 1</Title>
          <MaxScaleDenominator>750000</MaxScaleDenominator>
          <ogc:Filter>
            <ogc:PropertyIsEqualTo>
              <ogc:PropertyName>gs</ogc:PropertyName>
              <ogc:Literal>LA</ogc:Literal>
            </ogc:PropertyIsEqualTo>
          </ogc:Filter>
          <PointSymbolizer>
            <Graphic>
              <ExternalGraphic>
                <OnlineResource xlink:type="simple" xlink:href="UT/LA.svg" />
                <Format>image/svg+xml</Format>
              </ExternalGraphic>
              <Size>
                <ogc:Literal>10</ogc:Literal>
              </Size>
            </Graphic>
          </PointSymbolizer>
        </Rule>
      </FeatureTypeStyle>
      <FeatureTypeStyle>
        <Rule>
          <Name>Type 2</Name>
          <Title>Type 2</Title>
          <MaxScaleDenominator>750000</MaxScaleDenominator>
          <ogc:Filter>
            <ogc:PropertyIsEqualTo>
              <ogc:PropertyName>gs</ogc:PropertyName>
              <ogc:Literal>PA</ogc:Literal>
            </ogc:PropertyIsEqualTo>
          </ogc:Filter>
          <PointSymbolizer>
            <Graphic>
              <ExternalGraphic>
                <OnlineResource xlink:type="simple" xlink:href="UT/PA.svg" />
                <Format>image/svg+xml</Format>
              </ExternalGraphic>
              <Size>
                <ogc:Literal>16</ogc:Literal>
              </Size>
            </Graphic>
          </PointSymbolizer>
        </Rule>
      </FeatureTypeStyle>
