orientation display problem

I'm trying to use MapServer to display UK Ordnance Survey MasterMap vector
data, but I've been experiencing problems when it comes to Cartographic Text
The text angle is specifed in the GML as an integer representing 10ths of a
degree, rather than as a floating point number. In order to overcome this
I've been pre-processing the OS GML using awk, to divide the text
orientation value by 10.
I'm converting the pre-processed GML to ESRI Shapefiles before displaying
the map using MapServer. As an example, here's a snipet of my Mapfile:
NAME "Tidal Water"
EXPRESSION ("[descriptiv]" == "Tidal Water")
COLOR 0 153 255
Am I on the right track for rescaling the orientation value, or is there a
better way of doing this?
