</Mark> twice in generated SLD

[bartvde@…]

When using the following CLASS definition on a WMS client layer (native type is
polygon):

    CLASS
      NAME "< 25000"
      EXPRESSION ([INWONERS] < 25000)
      METADATA
      END
      STYLE
        COLOR 255 136 0
        OUTLINECOLOR 0 0 0
        SYMBOL "circle"
      END
    END

The generated SLD contains two end Mark elements.

So the original map is returned without the SLD applied.
