Tyler,

I haven't tested it, but I see there is a GetStyleString() and SetStyleString()
method on the ogr.Feature() in Python.  So you can use the GetStyleString()
to fetch the style, but you will need to put it in a regular attribute yourself
if you are writing to PostGIS or Shapefile.  Also, I don't think there is any
mechanism to tell MapServer to use a regular attribute as the source of
the style string, though I can see that this would be very useful.

Best regards,
