PointSymbolizer

A PointSymbolizer specifies the rendering of a "graphic symbol" at a point.
If you want to draw a graphic symbol and a text you would better use a ShieldSymbolizer.
Staring from r1793 PointSymbolizer supports Scalable Vector Graphics (SVG) as input images, see examples below.

allow_overlap	allow text to overlap the point image; true/false	false
