However, when I remove the OUTLINECOLOR directive the svg output file still has two copies of each label. Printing two copies of text is fairly common for rendering a shadow for vector graphics. It is not necessary for outlining the text for svg. Mapserver correctly distinguishes between the fill color and stroke/outline color in its svg text rendering. (Look at the svg text example in my original post). Without looking at Mapserver's code, my guess is that no shadow results in one copy on top of another (no offset). This cannot be detected in a raster image; it can in a vector image. > Your second anomaly is not clearly descibed. Do you mean the png is > NOT rotated and the SVG is?

Labels that should be rotated ccw are rotated correctly. Labels that should be rotated cw are not rotated at all - they remain horizontal. This second anomaly is the one I'd like to get resolved. One advantage in working with svg files is that they are text. I can remove the extra labels using a simple text editor application as a post processor. The label rotation anomaly presents a bigger challenge. I'm trying to avoid the obvious workaround - writing my own drawLabelCache routine, using mapscript, for rendering svg output. Thanks for your input.
