Yes, this was a common problem when I original did a bunch of test with 
Thomas. I was using a version of mapserv-6.1-dev in the original tests 
and put together this test suite:

http://imaptools.com:8080/svg-test/

Most all of these SVG files would display correctly in mapserver.

I just put the test suite back up and based on:

MapServer version 6.2.1 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG SUPPORTS=PROJ 
SUPPORTS=GD SUPPORTS=AGG SUPPORTS=FREETYPE SUPPORTS=CAIRO 
SUPPORTS=SVG_SYMBOLS SUPPORTS=ICONV SUPPORTS=FRIBIDI SUPPORTS=WMS_SERVER 
SUPPORTS=WMS_CLIENT SUPPORTS=WFS_SERVER SUPPORTS=WFS_CLIENT 
SUPPORTS=WCS_SERVER SUPPORTS=SOS_SERVER SUPPORTS=FASTCGI 
SUPPORTS=THREADS SUPPORTS=GEOS INPUT=JPEG INPUT=POSTGIS INPUT=OGR 
INPUT=GDAL INPUT=SHAPEFILE

I looks like I'm seeing a lot more failures.

The trick was to flatten the SVG and save them a plain. Basically some 
complex and nested symbols did not work and text objects needed to be 
exploded to vectors.

I remember that there was some discussion about svg libraries and 
licensing issues the impacted this but I forget the details.

Thomas - can you summarize the issues again?

Thanks,
